Question

What is the wave speed of a wave that has a frequency of 200 Hz and a wavelength of 0.40 m?

Answer 1

`80(m)/(s)`

Explanation:

we know that

`Wave\ speed = (frequency) * (wavelength)`

Inn this problem we have

`frequency=200\ Hz`

`wavelength=0.40\ m`

substitute the values

`Wave\ speed = 200*0.40=80(m)/(s)`
