Waves
The document discusses different types of waves, including water waves generated by wind. It explains how wind blows over water and generates ripples and waves, which can grow large during storms when the wind blows consistently in one direction. The document also describes how waves behave in different environments, including entering shallow water where they slow down and break on shorelines.
Waves notes
This document discusses different types of waves, including their causes, characteristics, and behaviors. It defines key wave terminology like crest, trough, wavelength, and period. Wave size is determined by wind strength, duration, and fetch. Deep water waves travel in orbits while shallow water waves feel the bottom and change shape as they reach shore. Breakers come in spilling, plunging, and surging types. Longshore currents move sand along beaches, while rip currents pull water back out to sea. Tsunamis and rogue waves present unique wave hazards.
Waves
Waves are rhythmic movements that carry energy through matter or space caused by varying wind speeds. A wave has a crest, which is its highest point, and a trough, its lowest point. The wavelength is the distance between two adjacent crests, while the amplitude is half the wave's height. Frequency refers to the number of waves passing a point within a certain time period. Wave size depends on wind strength and duration, with gentler breezes causing ripples and stronger winds producing larger waves. While water appears to move forward with waves, it actually returns close to its original spot; only the wave's energy moves forward. Tsunamis differ in being caused by undersea earthquakes rather than wind.
Wave motion bsc
This presentation discusses various topics related to wave motion, including:
1. The wave equation, which is an important differential equation used to describe waves in various fields like acoustics and fluid dynamics.
2. Plane progressive waves in fluid media, which travel continuously in the same direction without changing amplitude.
3. The principle of superposition, which states that when two or more waves pass through the same medium at the same time, the net displacement at any point is the sum of the individual wave displacements.
accoustic
The document discusses key concepts related to acoustics and the behavior of sound in enclosed spaces. It defines terms like wavelength, period, frequency, velocity of sound, and amplitude. It then explains how sound waves interact with the materials and geometry of an enclosure through reflection, absorption, refraction, diffusion, diffraction, and transmission. Reducing the intensity of sound and absorbing sound through surfaces and audiences can control how sounds behave in an enclosed area. Reflections from right-angled corners and dispersion of enclosure sides also impact sound behavior.
Waves - Swell, Types, Reflection, Refraction, Tsunamis
The document summarizes key concepts about ocean waves. It describes how wind generates sea and swell, with sea being wind-driven waves and swell being uniform waves that travel outward from storm areas. Wave energy is affected by wind speed, duration, and fetch (distance over which wind blows). Wave height increases as waves enter shallower water and become steeper, eventually breaking in different types - spilling, plunging, or surging - depending on sea floor slope. The document also discusses wave refraction, reflection, tsunamis, and historical tsunami events.
Stresses due to seismic waves
This document summarizes different types of seismic waves and their effects. There are two main types of body waves (P and S waves) that travel through the earth's interior, and two main types of surface waves (Rayleigh and Love waves) that travel along the surface. Seismic waves are caused by earthquakes and can damage buildings by weakening their strength. To reduce damage, buildings can be constructed with base isolation devices, seismic dampers, or resistant structures like rectangles, arches, or triangles that are less affected by seismic waves. Critical structures like hospitals also require special precautions.
Earthquake
The document discusses earthquakes and seismic waves. It explains that the focus is the location inside the earth where an earthquake starts, while the epicenter is the point directly above the focus on the surface. The amount of damage depends on the depth of the focus - shallow foci cause more damage since the energy doesn't have to travel as far. There are three main types of seismic waves - P waves, S waves, and L waves. P waves arrive first, followed by S waves, and then L waves, which travel along the surface. Seismographs are used to record seismic waves and determine the magnitude, duration, and location of earthquakes.

Unit vi ANTENNA AND WAVE PROPAGATION
There are three main modes of radio wave propagation: ground-wave propagation for frequencies below 2 MHz, sky-wave propagation between 2-30 MHz, and line-of-sight propagation for frequencies above 30 MHz. Vertical polarization is superior to horizontal polarization for surface wave propagation. Wave tilt occurs at the earth's surface and changes the orientation of vertically polarized ground waves, causing them to contain both vertical and horizontal electric field components that are out of phase, converting the wave to elliptical polarization.
Waves and Water Dynamics
Waves are moving energy caused by various forces. There are different types of waves including transverse waves which move side-to-side and longitudinal waves which involve push-pull motions. Key wave characteristics include the crest, trough, wavelength, height, period, and steepness. Wave behavior changes based on water depth, resulting in deep-water, shallow-water, and transitional waves. Ocean waves are influenced by processes such as shoaling, refraction, diffraction, interference, and breaking on shorelines. Tsunamis are extremely long seismic sea waves that can cause catastrophic damage when making landfall.
Chapter 11-earthquakes
Earthquakes are caused by the buildup and sudden release of stress along faults within the Earth. As tectonic plates push against each other, stress accumulates until rocks break, causing vibrations called seismic waves. There are three types of faults defined by the direction of rock movement: normal faults occur when rocks pull apart due to tension, reverse faults occur when rocks are pushed together by compression, and strike-slip faults occur when rocks slide past one another due to shear forces. Seismographs are used to measure the seismic waves and locate the epicenter, or surface point above the underground hypocenter where rock movement begins.
Earthquakes and tsunamis by Omar Calleja, 3.03
Earthquakes are caused by a sudden release of energy in the Earth's crust that creates seismic waves. The largest earthquakes in history have been around magnitude 9. Tectonic earthquakes occur anywhere there is sufficient stored elastic strain energy to drive fault propagation. Aftershocks are smaller earthquakes that occur after a mainshock in the same region.
Tsunamis are large sea waves caused by earthquakes, landslides, volcanic eruptions, and other underwater disturbances. They can devastate coastal regions due to their immense volume of water and high energy. As tsunamis approach shore and waters shallow, their velocity decreases but they can still cause damage through their powerful waves and ability to drain land and carry debris
Detailed study of Seismic Waves [Research]
Seismic waves originate from the breaking of rocks during earthquakes. There are different types of seismic waves including P-waves, S-waves, and surface waves. Seismology is the study of seismic waves and earthquakes, which has been practiced for around 150 years. Seismic waves can be used to determine the location and depth of the earthquake focus, and to measure the size of earthquakes using scales like the Modified Mercalli scale and Richter scale. Earthquakes caused by seismic waves can damage buildings and infrastructure, cause injuries and loss of life, trigger events like liquefaction and landslides, and in some cases generate destructive tsunamis.
EARTHQUAKE
Earthquakes are caused by the movement of tectonic plates underground. There are three types of waves produced by earthquakes: P-waves, which move through solid material; S-waves, which move perpendicular to the direction of the wave; and surface waves, which travel along the Earth's surface. Earthquakes are measured using seismographs, which record the direction and timing of the different waves, and scales like the Richter scale and Mercalli scale, which measure the intensity and effects of the earthquake. Major historical earthquakes include ones in Shansi, China in 1556 that killed 83,000 people and in Kolkata in 1737 that killed 300,000 people.
Earthquakes Notes
This document defines key terms related to earthquakes and seismic waves. It explains that earthquakes are caused by a sudden release of energy along fault lines in the earth. The focus is the location within the earth where the earthquake starts, while the epicenter is the point on the surface directly above the focus. There are three main types of seismic waves: P-waves which move in the direction of travel, S-waves which move sideways, and surface waves which cause the most damage. The timing and speed of P and S waves detected by seismic stations can be used to locate the epicenter of an earthquake.
Presentation About Seismic Wave
1. Earthquakes generate seismic waves that travel through the earth's crust and cause the ground to shake when they reach the surface.
2. The characteristics of earthquake ground shaking, such as duration, amplitude, and frequency, are important for how buildings respond.
3. A building's natural frequency determines how much it will vibrate in response to seismic waves - if the ground motion matches this frequency, resonance can amplify shaking and damage.
Earthquake Terminology & causes
This document discusses earthquake terminology and concepts. It defines key terms like epicenter, hypocenter, magnitude, and intensity. It explains what causes earthquakes, including the movement of tectonic plates. It also briefly discusses tsunamis and methods of earthquake-proofing buildings to withstand seismic activity, such as using flexible materials and separating base columns from the ground.
Tsunamis
Tsunamis are large sea waves caused by underwater disturbances like earthquakes, landslides, volcanic eruptions, and explosions. They can cross oceans with long wavelengths and periods but grow dramatically in height when they reach shallow waters near coastlines, flooding land areas and posing a major risk. Tsunamis are difficult to predict and prevent because they travel so quickly across oceans and their triggers are not always detectable, though earthquakes near bodies of water can serve as warning signs. The 2004 Indian Ocean tsunami showed how destructive they can be, altering landscapes and killing thousands in Southeast Asia.
Earth quake resistant structures
This document discusses methods for earthquake resisting construction. It begins by defining earthquakes and seismic waves, then discusses different types of seismic waves and how their movement causes shaking. It also covers where earthquakes typically occur and how their magnitudes are measured. The document then examines the impacts of earthquakes and how buildings can collapse. Finally, it presents several methods for improving earthquake resistance in structures, such as using shear walls, dampers, and designing foundations to avoid liquefaction or weak soils.
Tides and tsunamis lrg
The document discusses various types of ocean waves including tides, tsunamis, and seiches. It explains that tides can be spring or neap depending on the relative positions of the sun and moon, and can be diurnal, semidiurnal, or mixed depending on their daily cycles. It also discusses how interference patterns from multiple wave sources can cause tides to constructively or destructively interfere in different locations.
Ocean waves
The document discusses wave generation and properties. It explains that wind transfers energy to water, creating ripples and waves. Wave size depends on wind speed, direction, duration, and fetch. As waves move away from the wind area, they become swells with long periods and amplitudes. In shallow water, waves slow down, steepen, and eventually break when the height to length ratio reaches 1:7. The document also covers wave classifications, properties of deep water waves, pressure contours, and effects of waves on ship operations like motions, slamming, and speed loss.
Mulvey power point for earthquake vocabulary
The document discusses earthquakes, including what causes them, how they are measured, and their effects. It defines earthquakes as occurring along faults in the earth's crust due to a buildup of pressure. When the pressure is released, seismic waves are generated and cause shaking and damage at the epicenter and surface. Earthquakes are measured by both magnitude scales and intensity scales that indicate their strength and damage. Major earthquakes can cause widespread destruction through ground shaking and secondary effects like tsunamis and landslides.
Earthquakes and Faults
This three paragraph summary provides an overview of key information from the document:
The document discusses different types of faults including dip-slip faults, reverse faults, and strike-slip faults which form at diverging, converging, and transform plate boundaries. Earthquakes occur when built up stress is released along these faults, sending seismic waves. There are three main types of seismic waves: P-waves, S-waves, and surface waves. The 1999 Taiwan earthquake that is the focus of the document measured 7.6 on the Richter scale and caused catastrophic damage across the island.
1 the nature of waves (7.1)
- Scientists use models of waves to gain a better understanding of light, which behaves similarly to waves in some respects.
- All waves transfer energy through a medium without transferring matter. A wave's medium can be water, air, or another substance.
- Mechanical waves require a medium and are generated by a source, such as a vibrating guitar string. They can be transverse, with vibration perpendicular to the energy's direction, or longitudinal, with vibration parallel to it.
- A wave pulse is a single disturbance passing through a medium, while continuous waves repeat due to an oscillating source, carrying energy away continuously. Sound and light exhibit properties of waves.
Earthquake Vocabulary

Interactions of waves11
Waves can interfere when they overlap in space. Constructive interference occurs when wave amplitudes add, increasing the overall amplitude. Destructive interference occurs when wave amplitudes subtract, decreasing the overall amplitude. When waves reflect off surfaces, the angle of incidence equals the angle of reflection according to the law of reflection. Refraction occurs when waves pass from one medium to another with a different speed, causing the waves to bend. Standing waves form when waves reflect back on themselves, creating nodes of no displacement and antinodes of maximum displacement.

Destructive interference happens when wave amplitudes subtract, decreasing the overall amplitude. Reflection is when a wave bounces off a surface, obeying the law of reflection. Refraction is when a wave changes speed and direction as it enters a new medium. Standing waves form from the interference of traveling waves reflecting back on themselves, creating nodes and antinodes. Resonance amplifies vibrations at an object's natural frequency.
Waves
Waves are disturbances that transfer energy through a medium. Simple harmonic motion describes periodic oscillations where the restoring force is proportional to displacement. Characteristics of waves include amplitude, period, frequency, and wavelength. Mechanical waves require a medium while electromagnetic waves do not. When waves interact with boundaries, they exhibit reflection, refraction, diffraction, and interference according to the principles of superposition.
Glossary of scientific terms to know.pdf
This document provides definitions for over 100 scientific terms across various fields including physics, chemistry, biology, and more. Some key terms defined include:
- Pressure wave - a variation in pressure that propagates as a sound wave
- Wave - a disturbance that transfers energy through a medium without transferring matter
- Wave velocity - the distance a wave travels per unit of time within a medium
- Field effect - the modulation of a material's conductivity by an external electric field
- Wave node and antinode - points along a standing wave where the amplitude is at a minimum or maximum
- Surface wave - a mechanical wave that propagates along the interface between different media
Propagation Of Waves
1. Waves propagate or spread outward from their origin through a medium such as air.
2. Electromagnetic waves are created by local disturbances in electric and magnetic fields and propagate uniformly in all directions through a uniform medium.
3. Radio waves can propagate from transmitting to receiving antennas through either ground waves, which travel near the Earth's surface, or sky waves, which are reflected back by the ionosphere.
Interference
This document discusses interference, which occurs when two or more waves overlap. There are two types of interference: constructive and destructive. Constructive interference occurs when waves are displaced in the same direction and amplitudes add, while destructive interference occurs when they are displaced in opposite directions and amplitudes subtract. The document provides examples of interference in light, radio, acoustic, and water waves. It describes Young's double-slit experiment, which demonstrated that light behaves as waves that can interfere and was evidence against the particle theory of light.

The document discusses different types of wave interactions including reflection, scattering, refraction, diffraction, absorption, and interference. Reflection causes waves to bounce back at the same angle they hit an object. Scattering is a type of reflection where waves reflect in many directions after colliding with matter. Refraction causes waves to bend when moving between materials with different propagation speeds. Diffraction occurs when waves bend around barriers or through openings. Absorption transfers energy from waves to objects. Interference involves overlapping waves that can either constructively or destructively combine by increasing or decreasing amplitude.
Waves
The document discusses reflection, refraction, and diffraction of waves. A ripple tank experiment is described where a light shines through a tank of water onto a sheet of paper below, allowing the movements of water wave crests and troughs to be observed. Reflection occurs when waves bounce off barriers, following the law of reflection. Refraction is when waves change direction at a medium boundary due to speed and wavelength changes. Diffraction is the bending of waves around obstacles.

This document describes characteristics of electromagnetic waves and their behavior. It discusses how oscillating charges can generate electromagnetic waves, and how these waves consist of oscillating electric and magnetic fields that propagate perpendicularly. It also covers how electromagnetic waves transfer energy between electric and magnetic fields as they travel at the speed of light.
Ppt Waves
Waves transfer energy and are made up of pulses. There are two main types of waves: transverse waves, where particle movement is perpendicular to velocity, and longitudinal waves, where particle movement is parallel to velocity. Longitudinal waves have two parts - compressions where particles are closer together, and rarefactions where they are farther apart. When two waves meet, their amplitudes add through interference and superposition, which can make the combined wave bigger or smaller.

This document discusses different types of waves, including mechanical and electromagnetic waves. It covers key properties and concepts such as wavelength, amplitude, frequency, velocity, interference, reflection, refraction, diffraction, standing waves, and the Doppler effect. Mechanical waves require a physical medium and include transverse, longitudinal and surface waves, while electromagnetic waves use electric and magnetic fields and include phenomena such as light.
Unit 30 Wave Properties
Waves are disturbances that transfer energy through a medium such as water, air, or solids. There are three main types of mechanical waves: surface waves, which travel along the surface between two media; longitudinal waves, which compress and expand the medium; and transverse waves, where the medium moves at right angles to the wave. Key wave properties include frequency, wavelength, amplitude, speed, reflection, refraction, interference, and diffraction.
WAVES-GROUP-1.pptx
Waves are rhythmic disturbances that transfer energy through a medium or space. There are two main types of waves: mechanical waves, which require a medium, and electromagnetic waves, which do not. Mechanical waves can be transverse, with a perpendicular motion, longitudinal, with a parallel motion, or surface waves with circular motion. The properties of waves include wavelength, frequency, amplitude, and speed. Waves transfer energy through a medium by moving its particles in an up and down or back-and-forth motion without moving the medium itself.
Architectural acoustics
Sound is a disturbance that passes through a medium as longitudinal waves, causing the sensation of hearing. The speed of sound differs depending on the molecular composition of the medium. When sound waves encounter barriers in an enclosed space, they can be reflected, absorbed, refracted, diffused, diffracted, or transmitted. Reflection occurs when the wavelength is smaller than the surface, causing the waves to hit the enclosure continuously until the energy reduces to zero. Absorption occurs when some of the wave's energy is lost through transfer to barrier molecules. Refraction is the bending of sound waves when passing between different media. [END SUMMARY]
Waves and Sound - Copy.ppt
1. A mechanical wave is a disturbance that propagates through a medium with little net displacement of particles. Sound waves are an example of mechanical waves.
2. The speed of a wave depends on the medium and can be calculated from the wavelength and frequency. The speed of sound in air is about 340 m/s.
3. Waves can be transverse, involving side-to-side motion perpendicular to the direction of travel, or longitudinal/compressional, involving back-and-forth motion parallel to the direction of travel.
Waves
Waves are disturbances that transfer energy through a medium. They are caused by vibrations in the medium and can be transverse, longitudinal, or a combination. Key properties of waves include amplitude, wavelength, frequency, and speed. Waves interact with each other and surfaces through reflection, refraction, diffraction, interference, and can form standing waves through the combination of incoming and reflected waves.
Waves
Waves transfer energy through a medium without transferring matter. There are two main types of waves: transverse waves, where the medium's particles move perpendicular to the wave's direction; and longitudinal waves, where particles move parallel. Characteristics like wavelength, frequency, amplitude, and speed define a wave's properties. Energy is transferred through reflections, where waves bounce back at the same angle they arrive. Reflections can be partial or total, depending on the boundary material.
