Question

We know that the speed of sound depends on frequencyand wavelength, v=lambda x frequency. But the velocity of the wave on the medium is constant if elasticity and temperature is not changed, why so? Also if we change the frequency of sound from the source why does the speed not change?

Answer 1

Dear Student

the velocity of sound wave depends on the elasticity and the temperature as they change the velocity will also change.
Elasticity is the property which show that how quickly a particle come on their original position, if material is less elastic velocity of sound will be less and in more elastic material velocity will be more. If will take the case of temperature in case of the solid and liquid material velocity increases as the temperature increase because the kinetic energy of the particle will increase as the temperature increase. As the frequency increase the wavelength decrease so resultant velocity in the medium will be constant
