Question

If a wave has a wavelength of 20 meters and is

traveling at a rate of 60m/s, what is its
frequency?

Answer 1

Frequency of wave = 3 Hertz

Explanation:

Given that:

Wavelength of wave = 20 meters

Velocity of wave = 60m/s

We know that:

v = fλ

Here,

v = velocity , f = frequency and λ = wavelength

Putting values in formula

60 = f(20)

20f = 60

Dividing both sides by 20

`(20f)/(20)=(60)/(20)`

f = 3 Hertz

Hence,

Frequency of wave = 3 Hertz
