A wave has a wavelength of 3 meters and a Frequency of 15Hz. what is it’s velocity?

Velocity of wave = 45 m

Explanation:

Given

wavelength = 3 m

Frequency = 15 Hz = 15

Velocity = ?

We know that for all waves, the relationship between wavelength λ, frequency f and velocity v is same and given by the equation:

                           v = fλ

Hence, Velocity of wave = 15 x 3 m

                                         = 45 m

the part of the wave he is travelling on is the crest
