Question

which of these is a description of wave frequency? how far apart two waves are how often waves pass a given point

Explanation:

Wave frequency is defined as the number of waves that pass a fixed point in a given amount of time. The option "how often waves pass a given point" aligns with this definition. The other option "how far apart two waves are" describes wavelength, not frequency.

Answer:

"how often waves pass a given point" is the correct description of wave frequency.
