Question

What is the wave speed of a wave that has a frequency of 250 Hz and a wavelength of 0.35 m?

Answer 1

Speed = (frequency) x (wavelength)

Speed = (250Hz) x (0.35m)

Speed = 87.5 m/s

Answer 2

Answer: The correct answer is 87..5 m/s.

Step-by-step explanation:

The expression for the relation between the speed of the wave and the frequency of the wave is as follows;

`v=f\lambda`

Here, v is the speed of the wave, f is the frequency and
`\lambda` is the wavelength of the wave.

It is given in the problem that a wave has a frequency of 250 Hz and a wavelength of 0.35 m.

Put f=250 Hz and
`\lambda`= 0.35 in the above expression.

`v=(250)(0.35)`

`v=87.5 m/s`

Therefore, the wave speed of a wave is 87.5 m/s.
