Question

An oscillator is used to create a wave on a string. The frequency of the oscillator is 4 Hz and the waves measures to be 0.5 m apart. What is the speed of the wave

Answer 1

Given,

Frequency of the wave, f=4 Hz

The wavelength of the wave, λ=0.5 m

The speed of a wave is given by,

`v=f\lambda`

On substituting the known values in the above equation,

`v=4*0.5=2\text{ m/s}`

Therefore the speed of the standing wave produced is 2 m/s
