the following videos are of sound energy moving through a medium made up of gas particles. watch video a and video b. compare the difference and select the correct differences below. pick all that apply.
video a
video b
a video b is of a high amplitude sound wave and therefore has more energy
b video b is of a low amplitude sound wave and therefore has less energy
c video a is of a high amplitude sound wave and therefore has more energy
d video a is of a low amplitude sound wave and therefore has less energy

Explanation:

Amplitude of a sound wave corresponds to the degree of particle compression/rarefaction. Higher amplitude means more particle displacement, which equals more sound energy. Video A shows greater particle spacing variation (higher amplitude) than Video B, so Video A has more energy, and Video B has lower amplitude/less energy.

Answer:

B. Video B is of a Low Amplitude Sound Wave and therefore has less energy
C. Video A is of a High Amplitude Sound Wave and therefore has more energy
