Question

A wave has a frequency of 450 Hz and a wavelength of 0.52 m. What is the

speed of the wave?
Use V = fx.
A. 230 m/s
B. 0.0012 m/s
C. 870 m/s
D. 0.042 m/s

Answer 1

A. 230 m/s

Step-by-step explanation:

The speed of a wave is given by:

`v=f \lambda`

where

f is the frequency

`\lambda` is the wavelength

For the wave in the problem,

f = 450 Hz (frequency)

`\lambda=0.52 m` (wavelength)

Substituting into the equation, we find the speed:

`v=(450)(0.52)=234 m/s \sim 230 m/s`
