Question

A wave with a wavelength of .050 m travels at 220 m/s. What is its frequency?

Answer 1

Answer:The frequency of a wave with wavelength of 0.050 m and speed of 220 m/s is 4.4 kHz.

Step-by-step explanation:

Frequency is the measure of repetition of a cycle in a given time. So it is inversely proportional to the wavelength and directly proportional to the speed.

As wavelength is the measure of distance covered by the wave and speed is the rate at which the distance is covered. Frequency will be the number of times a complete cycle will be repeated in that particular time.

Here the wave speed is given as 220 m/s and wavelength is given as 0.050 m.

Then

Thus, the frequency of a wave with wavelength of 0.050 m and speed of 220 m/s is 4.4 kHz.

Answer 2

The frequency of a wave with wavelength of 0.050 m and speed of 220 m/s is 4.4 kHz.

Step-by-step explanation:

Frequency is the measure of repetition of a cycle in a given time. So it is inversely proportional to the wavelength and directly proportional to the speed.

`Frequency =\frac{\text { Wave speed }}{\text { wavelength }}`

As wavelength is the measure of distance covered by the wave and speed is the rate at which the distance is covered. Frequency will be the number of times a complete cycle will be repeated in that particular time.

Here the wave speed is given as 220 m/s and wavelength is given as 0.050 m.

Then
`\text { Frequency }=(220)/(0.050)=4400 \mathrm{Hz}`

Thus, the frequency of a wave with wavelength of 0.050 m and speed of 220 m/s is 4.4 kHz.
