Waves document
This document defines key terms used to describe wave behavior such as amplitude, frequency, period, wavelength, and velocity. It explains that amplitude is the maximum displacement from equilibrium, frequency is the number of events per unit of time, and period is the time for one oscillation. For waves, amplitude is the distance between resting and maximum displacement, frequency is the number of waves passing per second, and period is the time for one wave cycle. Wavelength is the distance between identical parts of a wave and velocity is the speed at which the wave disturbance propagates. Graphs and examples of water waves are provided to illustrate these concepts. Equations show the relationships between frequency, period, wavelength and velocity.

General properties of wave
Waves transfer energy from one point to another without physical transfer. There are two main types of waves: transverse waves where the vibration is perpendicular to the direction of travel, like water waves; and longitudinal waves where the vibration is parallel to the direction of travel, like sound waves. The key properties that describe a wave are its amplitude, wavelength, frequency, and period. The frequency is the number of waves that pass a point per second, while the period is the time for one full wave.
Waves
This document discusses different types of waves including longitudinal waves, transverse waves, and how their amplitude, wavelength, frequency, velocity, and other properties are defined. It explains that longitudinal waves have particles that vibrate parallel to the direction of energy transport, while transverse waves have particles that vibrate perpendicular to the direction of energy transport. It also covers the concepts of reflections, refraction, and how waves behave when passing between different media.
Waves
Waves are disturbances that propagate or move from the place they were created. For water waves, the disturbance is on the water surface, created by things like rocks or splashing. For sound waves, the disturbance is changes in air pressure, created by speakers. All waves have characteristics like amplitude, period, frequency, and velocity. Wave velocity is the speed at which the disturbance propagates, measured as the distance traveled per period. This relationship between wavelength, period, and velocity holds for all types of waves.

Waves are vibrations that propagate through a medium, carrying energy from one place to another. Periodic waves repeat in a regular pattern with a continuous disturbance. Key wave terminology includes the crest, trough, amplitude, wavelength, frequency, period, and velocity. Waves can be mechanical (requiring a medium) or electromagnetic (not requiring a medium).

Okay, here are the steps:
- Frequency (f) = 4 Hz
- Wavelength (λ) = 0.75 m
- Use the formula: Speed (v) = Frequency (f) x Wavelength (λ)
- v = f x λ
- v = 4 Hz x 0.75 m
- v = 3 m/s
Therefore, the speed of the transverse wave is 3 m/s.

WAVES
Waves are caused by wind dragging across the surface of water, causing the water to oscillate rather than move as a solid block. Individual water particles move in circles while the wave energy travels forward. Key characteristics of waves include their height from trough to crest, wavelength between two crests, and period of time for one full wavelength to pass. Wave size depends on wind speed, duration, and the distance of open water over which the wind blows known as fetch. As waves approach shore, their speed decreases causing their height to increase and wavelength to decrease, sometimes causing waves to break.

Teacher's Guide for discussion about the nature, categories and characteristics of waves. For grade 7 lesson, quarter 3, module 2
Physics chapter 7
This document discusses waves and sound. It defines waves as periodic motions that transfer energy through a medium without permanently displacing particles. It describes two types of waves - transverse waves, where the medium moves perpendicular to the wave direction, and longitudinal waves, where the motion is parallel. Sound waves are longitudinal waves that propagate via vibration in air, water or other materials. The velocity of sound depends on factors like the medium, temperature and humidity. Bats use echolocation to navigate by emitting ultrasonic sounds and interpreting the echoes. The document also discusses how echo and sound velocity can be used to measure well depths.
Waves ii
Waves can transfer energy through a medium and come in different types. A longitudinal wave transfers energy through a medium by causing particles to vibrate parallel to the direction of energy transfer, like sound waves. A transverse wave transfers energy through a medium by causing particles to vibrate perpendicular to the direction of energy transfer, like water waves. The key parts of a wave include its amplitude, wavelength, frequency, and period. The speed of a wave can be calculated by multiplying its frequency and wavelength.

It also defines key terms related to oscillations such as period, frequency, amplitude, damped oscillations, and sustained oscillations. Regarding waves, it describes longitudinal and transverse waves, and defines properties such as wavelength, velocity, and how velocity is related to frequency and wavelength. It also provides formulas for calculating the velocity of longitudinal and transverse waves in different media.
MAHARASHTRA STATE BOARD PHYSICS Chapter 6 - SOUND
The document discusses sound waves and their properties. It begins by asking how students know when a class is over, noting they hear the school/college bell. It then discusses different types of waves like longitudinal waves, which have particles vibrating parallel to the direction of propagation like sound waves. Transverse waves have particles vibrating perpendicular to the direction of propagation. Key properties of waves discussed include amplitude, wavelength, frequency, period, and velocity. The document is a chapter from a physics textbook that provides information on sound waves and summarizes different wave types and their characteristics.
Sound
Sound waves are longitudinal waves that propagate through a medium by causing oscillations in pressure. The speed of sound depends on properties of the medium like density and bulk modulus. Frequency determines pitch, with the human hearing range from 20-20,000 Hz. The Doppler effect causes changes in observed frequency due to relative motion between source and receiver. Sonar uses echoes to locate objects by sound, while sonic booms occur when the source moves at or faster than the speed of sound.

How to Manage Reception Report in Odoo 17
A business may deal with both sales and purchases occasionally. They buy things from vendors and then sell them to their customers. Such dealings can be confusing at times. Because multiple clients may inquire about the same product at the same time, after purchasing those products, customers must be assigned to them. Odoo has a tool called Reception Report that can be used to complete this assignment. By enabling this, a reception report comes automatically after confirming a receipt, from which we can assign products to orders.
THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

Wave and its properties
- 3. PARTS OF THE WAVE
- 4. CREST - the highest point of the wave. TROUGH - the lowest point of the wave. AMPLITUDE - is the displacement from the resting position to the highest (or lowest) point of the wave. WAVELENGTH – is the distance from one point to the next identical point of the wave.
- 5. FREQUENCY – describes how often a vibration occurs. It also specifies how many complete vibrations occur at a given time (usually one second). 1 1 F = or T Period * The SI Unit of frequency is the HERTZ (Hz) , equivalent to one cycle per second.
- 6. PERIOD – is the time needed to complete one vibration. 1 1 T = or F Frequency
- 7. WAVE SPEED - is the rate at which the wave travels through a particular point. Wave speed = Frequency x Wave length or wavelength Wave speed = period
- 8. WAVELENGTH – distance from crest to crest. The wavelength λ of a sinusoidal waveform traveling at constant speed v is given by: v λ = f where v is called the phase speed (magnitude of the phase velocity) of the wave and f is the wave's frequency.
- 9. LOUDNESS - physiological sensation that varies from one person to another. It depends on the sense of hearing. INTENSITY (I) - depends on the amplitude of pressure variations within the sound waves. The unit used for sound intensity level (B) is decibel (dB) , named after Alexander Graham Bell. QUALITY – enables to identify the source of sound because tones differ from one another. PITCH – refers to the highness or lowness of a tone. It is related to frequency.
- 10. REFLECTION OF WAVE a.) REFRACTED- when wave travel from one medium to another. b.) DIFFRACTED- when wave pass through a narrow opening and interfere when they interact with other wave.
- 11. TRANSVERSE WAVE The vibrational direction of the particles in the medium is up and down perpendicular to the direction of the wave.
- 12. LONGITUDINAL WAVE The vibrational direction of the particles of the medium is parallel to the direction of the wave.
