Question
What factors affect the frequency of a wave?
A. the amplitude
B. the energy of the wave
C. the wavelength of the wave
D. the material through which it travels
E. the velocity of the wave
I said C,D, and E. Should there be anything else?

The real answer is none of the above.
The one thing that is hard to change about a wave is frequency.
There is no place to store the extra peaks :)
If ten crests pass point A per second, then ten have to pass point B per second. If the speed increases, the wavelength has to increase to keep the same frequency.
However I do not think that is what the question writer was thinking about.
I guess I would say C D and E because wavelength and velocity give frequency and velocity depends on material.
