UNIT 8 Listening Properties of Waves

Type your name. Please include first and last name to receive full credit Wave Mechanics Watch the video and answer the questions that follow Waves always originate with some person object distrubance Wave motion begins from a center point and moves to the left to the right outward in all directions A wave is how someone says hello a traveling disturbance that carries energy from place to place. A wave that travels through a material medium is called a radial wave linear wave mechanical wave The energy in a transverse wave moves _ to the direction of the medium. parallel perpendicular The energy in a longitudinal wave moves _ to the direction of the medium. parallel perpendicular Parts of a Longitudinal Wave match the correct part with the definition Compression "push" part of the wave where the particles are closest together Rarefaction "pull" part of the wave where the particles are furthest apart Fill the blank with the correct answer from the drop down With mechanical waves the mediumdoes not travel with the wave, just the energyis carried by the wave. So in the ocean the wavewill travel a great distance, but any individual water moleculewon't go too far, it's only the energythat travels along with the wave. Which type of waves are not mechanical waves; meaning they need no medium to travel through sound water electromagnetic (light) Parts of a Wave Match the correct part to the definition Amplitude (A) displacement of the wave measured from its equilibrium position. Distance from the middle to a crest or trough. Wavelength (λ) Length of one cycle; distance between corresponding points of two consecutive waves. Measured from one crest to the next Period (T) time required to complete one cycle of vibration to pass a given point Frequency (𝜈) number of waves per unit time measured in hertz (Hz). The number of crests of a wave that move past a given point in a given unit of time. Which of these cannot travel through the vacuum of space sound light energy The equation for the speed of a wave is frequency divided by Time frequency divided by wavelength wavelength times frequency wavelength times Time
