Question

The frequency of a wave with a velocity of 30.meters per second and a wavelength of 5.0 meters is
150 Hz
6.0 Hz
5.0 Hz
25 Hz

Answer 1

Answer:

Frequency of the wave is f = 6.0 Hz

Explanation:

As we know that the speed of the wave is

v = 30 m/s

now the wavelength is given as

$\lambda = 5 m$

now we know that frequency is the ratio of speed and wavelength of the wave

so we have

$f = \frac{30}{5}$

$f = 6 Hz$
