Sound refraction depends on the fact that the speed of sound is
A)constant.
B)variable.
C)proportional to frequency.
D)inversely proportional to wavelength.
E)None of the above choices are correct.

Question

Quizplus · Accepted Answer

Sound refraction occurs due to changes in the speed of sound as it passes through materials of varying densities. The speed of sound is not constant and can vary depending on the medium it is passing through. Therefore, option B is the correct choice. The other options are not correct as the speed of sound is not always proportional to frequency or inversely proportional to wavelength.
