Question

A student wants to determine experimentally whether sound travels faster through air or water. She could accomplish this by designing an experiment to measure the *

a) distance that the sound travels through each medium.

b) time required for sound to travel a fixed distance in each medium.

c) distance that the sound travels in each medium for various temperatures.

d) distance that the sound travels in each medium for different pitches.

e) frequency of the sound waves before entering either medium.

Answer 1

I would pick the "e" answer.....the perceived frequency (pitch) is proportional to the relative velocity of the source to that of the observer. This is the Doppler effect.

Maybe think of it this way: If the speed of sound in a material is zero, you will hear nothing at the output end (side) of the experiment
