select the correct answer from each drop - down menu. the number of waves that pass through a fixed point per second is the of the wave. this value increases when the of the wave decreases.

select the correct answer from each drop - down menu. the number of waves that pass through a fixed point per second is the of the wave. this value increases when the of the wave decreases.

Answer

Brief Explanations:

The number of waves that pass through a fixed - point per second is defined as the frequency of a wave. According to the wave equation $v = f\lambda$ (where $v$ is the wave speed, $f$ is the frequency, and $\lambda$ is the wavelength), when the wave speed $v$ is constant, frequency $f$ and wavelength $\lambda$ are inversely proportional. So frequency increases when the wavelength decreases.
