which of the following is an example of sound refraction?
a).sound waves bouncing off a canyon wall to create an echo
b).reverberations in a concert hall
c).a high pitch sound changing to a low pitch sound
d).sound waves changing direction as they encounter different air temperatures

Sound refraction occurs when the sound wave leaves one environment for another, causing a different wave refractive index. This passage ends up causing a change in the speed of propagation and a variation in the length of the sound wave. An example of this can be seen when you recognize reverberations in a concert hall.

This phenomenon does not happen only in sound waves, as it can also be observed in light.
