    I know that the frequency of light never changes. Does the frequency of sound change? One of the AAMC questions was in regards to sound going through a wall. I chose an answer that said the frequency would decrease because the sound would be going to a medium with a higher index of refraction. The explanation said frequency and wavelength would remain the same. Would the velocity decrease?
