Question
What will be the change in the wavelength of a sound wave in air if its frequency is doubled?
Advertisements
Solution
We know the relation between velocity, frequency, and wavelength
ν = f × λ,
where ν is the velocity, f the frequency, and λ the wavelength
Velocity of sound is constant for a given condition. Therefore, if wavelength is doubled, frequency is halved.
