Question

What is a wave frequency? A. the number of waves that pass a fixed point in a fixed period of time B. the speed that a wave is passed from particle to particle through a medium C. the loudness of a wave as it travels though the air D. the height of a wave between peak and trough

Answer 1

Frequency - number of waves (vibrations, revolutions, of cycles) that pass a given point per unit time.

the correct answer should be A

hope this helps :)

Answer 2

Answer:

A. the number of waves that pass a fixed point in a fixed period of time

Explanation:

A wave is a disturbance that travels in a medium. Frequency of a wave can be defined as the number of waves passing through a fixed time per second. It is measured in Hertz. Wavelength is the distance between two crests or troughs. Amplitude is half height of a wave between peak and trough.

Thus, option A is correct.
