Question

A periodic wave has a wavelength of 1.6 m and a speed of 16 m/s. What is the wave frequency?

Answer 1

10 Hz

Step-by-step explanation

Given:

• The wavelength of a periodic wave, λ = 1.6 m

,

• Its speed, v = 16 m/s

Find:

• The wave frequency, f

The frequency of a wave is given by the quotient between the wave's speed and its wavelength,

`f=(v)/(\lambda)`

Replace the known values and solve,

`f=(16m\/s)/(1.6m)=10\text{ }(1)/(s)=10\text{ }Hz`

Hence, the frequency of the wave is 10 Hz.
