The number of waves that pass through a fixed point per second is the of the wave. this value increases the of the wave decreases.

The correct answers are frequency and wavelength.

Explanation:

Frequency is defined as the number of waves that passes through a fixed point in a given time.

Wavelength is the distance between the two crests or the two troughs.

The frequency and the wavelength are inversely proportional to each other.

If the frequency of the wave increases then the wavelength of the wave decreases.

Therefore, the number of waves that pass through a fixed point per second is the frequency of the wave. This value increases when wavelength the of the wave decreases.
