Question

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

Answer 1

Answer;

= 0.05 seconds

Explanation;

The speed of a wave is given by the product of frequency and wavelength;

Speed = Frequency × wavelength

Thus;

Frequency = speed/wavelength

= 200/10

= 20 Hz

But; period = 1/ frequency

Hence; Period = 1/20

= 0.05 seconds
