Sound refraction depends on the speed of sound being
A)constant.
B)variable.
C)proportional to frequency.
D)inversely proportional to wavelength.
E)none of the above

Question

Quizplus · Accepted Answer

Sound refraction occurs when there is a change in the speed of sound as it passes from one medium to another or within a medium that has varying properties. This change in speed causes the sound wave to bend or refract. Therefore, refraction depends on the speed of sound being variable.
