Question

A sound wave has a frequency of 125 Hz and a speed 5000 m/s What is the wavelength of the wave

Answer 1

The wave length of the sound with parameters frequency of 125 Hz and a speed 5000 m/s is 40 meters

Given Data

velocity = 5000 m/s

frequency = 125 Hz

wavelength = ??

We know that the relationship between speed, frequency and wavelength is given as

v = fλ ----------------------------1

substitute our given parameters

5000 = 125 * λ

Divide both sides by 125

λ = 5000/125

λ = 40 m

Hence the wave length of the sound is 40 meters
