Question

A wave has a frequency of 15,500 Hz and a wavelength of 0.20 m. What is the

speed of the wave? Use the equation v=f>

Answer 1

3100 m/s

Step-by-step explanation:

The relationship between frequency and wavelength of a wave is given by the wave equation:

`v=f\lambda`

where

v is the speed of the wave

f is its frequency

`\lambda` is the wavelength

For the wave in this problem,

f = 15,500 Hz

`\lambda=0.20 m`

Therefore, the wave speed is

`v=(15500)(0.20)=3100 m/s`
