What is the frequency of a wave with a time period of $0.05 \mathrm{s}$?

A body vibrates with a time period of $2\times {10}^{-3} \mathrm{second}$ to produce a wave having a velocity of $1250 \mathrm{m}/\mathrm{s}$. Calculate its wavelength. 

The density-time graph at a particular point in the medium when a sound wave passes through that point, is shown below:

Find the time period and frequency of the wave.

The density-time graph at a particular point in the medium when a sound wave passes through that point, is shown below:

 If the velocity of wave is $340 \mathrm{m}/\mathrm{s}$, find its wavelength.

What kind of waves travel at a speed of $3\times {10}^8 \mathrm{m}/\mathrm{s}$?

How will you produce a transverse wave in a slinky hanging from a rigid support?

Which property of sound enables us to distinguish between the sounds produced by different sources?

What is the repeated reflection resulting in the persistence of sound in a large hall called?
