Awave travels at a speed of 74 m/s. if the distance between crests is 12 m,
what is the frequency of the wave? use f =

f = 6.17 hertz

Explanation:

A wave is said to be a disturbance  which travels through a medium. This disturbance that travels through the medium carries energy. Generally, it is a physical phenomenon that possess amplitude, wavelength and frequency.

Frequency = velocity / wavelength

F = v/∧

where

v = velocity

∧ = wavelength

v = 74 m/s

∧ = 12

wavelength is the distance between successive crest or trough.

F = v/∧

f = 74/12

f = 6.16666666667

f = 6.17 hertz
