Question

What is the period of a wave if the wavelength is 10 m and the speed is 200 m/s?

Answer 1

20 hertz

Explanation:

Given:

Speed of the wave =200 m/s

wavelength of the wave = 10 m

According to the formula :

Frequency=speed/wavelength

Frequency= 200/10

20 hertz or 20 wave periods per second

So, the number of periods of wave passing per second is 20
