This document defines different types of waves including transverse waves, longitudinal waves, and defines terms like supersonic speed and sonic boom. It explains that frequency is determined by speed divided by wavelength and discusses how water waves are visible because of the up and down motion of the water. It notes that sound is a longitudinal wave and gives the equation for speed of sound in air. It also relates pitch to frequency, defining low and high pitch sounds, and discusses ultrasonic and infrasonic waves. Finally, it states that amplitude determines how loud a sound is.
To know that sound can be reflected, refracted, diffracted, and produces interference effects.
Know that sound is a wave because it can be reflected and refracted as with particles, diffraction and interference only occur with waves

Sound waves are produced by the vibration of material objects. A disturbance in the form of a longitudinal wave travels away from the vibrating source. High-pitched sounds are produced by sources vibrating at high frequency, while low-pitched sounds are produced by low-frequency sources Sound waves consist of traveling pulses of high-pressure zones, or compression, alternating with pulses of low-pressures zones, or rarefaction. Sound can travel through gases, liquids, and solid, but not through a vacuum.
Identify sound waves in nature and physics, the type of piezowaves accompanying them, the difference between sound waves audible to humans and between ultrasound and subsonic waves, how to theoretically calculate their speed when they pass through different physical media, calculate their frequency and wavelength, and the effect of temperatures and the density of different materials on these calculations

Exploring Career Paths in Cybersecurity for Technical CommunicatorsBen Woelk, CISSP, CPTC
Brief overview of career options in cybersecurity for technical communicators. Includes discussion of my career path, certification options, NICE and NIST resources.
1. Transverse wave – A wave with a direction of propagation that is perpendicular to its direction of
oscillation
Longitudinal wave – A wave with a direction of propagation that is parallel to its direction of oscillation
Supersonic speed – Any speed that is faster than the speed of sound in the substance of interest
Sonic boom – The sound produced as a result of an object traveling at or above Mach 1
Pitch – An indication of how high or low a sound is, which is primarily determined by the frequency of
the sound wave
Frequency equals speed *v* divided by wavelength *that funny Greek letter at the bottom*.
(14.1)
You see them [the waves] because water heaves up and down. The crests and troughs that result from
such motion in the water produce visible waves. In physics terms, we say that water is the medium
through which the waves in the ocean travel.
Sound is a longitudinal wave.
The speed of sound in air is given by the following equation:
Sound waves with low pitch have low frequency.
Sound waves with high pitch have high frequency.
2. Waves with frequencies higher than 20,000 Hz are called ultrasonic waves, and waves with frequencies
below 20 Hz are called infrasonic waves.
The amplitude of a sound wave governs how loud the sound is.
