Question

A sound has a frequency of 262 Hz. The sound travels through water at 1435m/s. Find the wavelength for the sound when it is traveling through water.

Answer 1

Answer

Given, (In air)

Velocity V=340m/s

Frequency f=20,000Hz

Wavelegth λ=?

V=f.λ

λ=FV=20,000340=0.017Hz

Also, Given (in Water)

Velocity, V=1480m/s

Frequencyf=20,000Hz

wavelength, λ=?

V=F.λ

λ=FV=20,0001480=0.074Hz
