The Doppler effect describes a change in frequency or wavelength, caused by motion of the source, that is
A. only applicable to transverse waves.
B. only applicable to sound waves.
C. applicable to both sound and light (EM) waves.
D. only applicable when the wave is traveling through a medium such as air or water.
Homework Answers
Doppler effect is applicable to any wave in any medium. It only requires relative motion between the source and the observor.
So the answer is C. applicable to both sound and light waves.

When the source of a wave and an observer move either towards or away from each other the observed frequency of the wave will be different from the frequency at which the wave is emitted. For example, if you are standing by the side of the road and a police car with a siren passes by, the frequency of the sound you hear will be higher when the car is moving towards you and lower when it is moving away...

A sound wave a frequency of 20 kHz emerges through a circular opening that has a diameter of 0.78 m. Concepts: The diffraction angle for a wave emerging through a circular opening is given by sin(theta) = 1.22 /D, where is the wavelength of the sound and D is the diameter of the opening. What is meant by the diffraction angle? the angle that the sound wave bends away from the center before passing through the opening the location of...
