Question

Wave is traveling at 60 cm/second and has a wavelength of 15 cm, what is the frequency?

Answer 1

The frequency of the wave is 4 Hz

Explanation:

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

$v=f \lambda$

where

v is the speed of the wave

f is the frequency

$\lambda$ is the wavelength

For the wave in this problem, we have:

$v=60 cm/s$ is the speed

$\lambda=15 cm$ is the wavelength

Solving the equation for f, we find its frequency:

$f=\frac{v}{\lambda}=\frac{60 cm/s}{15 s}=4 s^{-1} = 4 Hz$
