the number of wave cycles per second is called the ________.
frequency
speed
energy
wavelength
red shift

Explanation:

In physics, the frequency of a wave is defined as the number of wave - cycles that occur per second. It is measured in hertz (Hz). Speed is the rate of change of position of a wave, energy is related to the amplitude and frequency of a wave, wavelength is the distance between two consecutive points in phase on a wave, and red - shift is a phenomenon related to the change in the wavelength of light due to the motion of the source or observer.

Answer:

A. frequency
