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

Answer:

50 Hz

Explanation:

The frequency of a wave is given by

$f=\frac{v}{\lambda}$

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

$f=\frac{60 m/s}{1.2 m}=50 Hz$
