Question

The wavelength of a wave on a string is 1.2 meters. If the speed of the wave is 60 meters/second, what is its frequency? A. 0.20 hertz B. 2.0 hertz C. 50 hertz D. 10 hertz E. 15 hertz

Answer 1

50 hertz

Step-by-step explanation:

Answer 2

50 Hz

Step-by-step explanation:

The frequency of a wave is given by

`f=(v)/(\lambda)`

where

v is the speed of the wave

`\lambda` is the wavelength

In this problem,

v = 60 m/s

`\lambda=1.2 m`

So the frequency is

`f=(60 m/s)/(1.2 m)=50 Hz`
