Question
Consider a wave that partially reflects and partially transmits when it reaches a boundary wherethe wave speed changes (due to a change of medium). Compare the effect of the change in
medium on the frequency and wavelength of the wave. i.e. How do the frequency and wavelength
of the reflected wave compare to the frequency and wavelength of the transmitted wave?
a. The wavelength changes but the frequency does not.
b. The frequency changes but the wavelength does not.
c. Both the frequency and wavelength change.
Explanation / Answer
a. The wavelength changes but the frequency does not.
