Question

If a wave travels at a speed of 60m/s and has a wavelength of 1.2m, what is its period?

Answer 1

The period is `=0.02s`

Explanation:

The speed of the wave is `v=60ms^-1`

The wavelength is `lambda=1.2m`

The equation of propagation of the wave is

`v=lambda f=lambda/T`

The period is `T=lambda/v=1.2/60=0.02s`
