Question

A wave has a frequency fo 240 Hz and a wavelength of 3.0. What is the speed of the wave?

Answer 1

The speed of the wave is
`v=(240)(3.0)=720.0`m/s

Explanation:

If `n` is the frequency of the wave
`lambda` is the wavelength of the wave
`v` is the speed of the wave,
the three quantities are related by
`v=nlambda`
We have,
`n=240`Hz
`lambda=3.0`m
`v=?`

Substituting
`v=(240)(3.0)=720.0`m/s
