Question

Calculate the wave speed of a 20 m wave that has a frequency of 10 Hz. *

Answer 1

Answer: 200metres per second

Explanation:

The wavespeed of a wave is the distance covered by the wave in one second. It is measured in metre per second, and represented by the symbol V.

Recall that Velocity (V) = Frequency F x wavelength λ

V = F λ

In this case, wavelength (λ)= 20 m frequency = 10 Hz.

Hence, V = F λ

= 20 metres x 10 hertz

= 200 metres per second

Thus, the wave travels at a speed of 200 metres per second
