If the bulk modulus of water is 2100 MPa, what is the speed of sound in water?

If speed of sound in air at 0°C is 331 m/s. What will be its value at 35° C?

For a progressive wave, in the usual notation

At normal temperature, for an echo to be heard the reflecting surface should be at a minimum distance of ………………. m.

In a transverse wave, are regions of negative displacement.

If pressure of air gets doubled at constant temperature then velocity of sound in air …………

Wave motion has …………

The speed of the mechanical wave depends upon …………

Longitudinal waves CANNOT be …………

Wavelength of the transverse wave is 30 cm. If the particle at some instant has displacement 2 cm, find the displacement of the particle 15 cm away at the same instant.
