Solve the following example:
A sound wave passes over a fixed point in space. Ten compression and ten rarefactions pass the point in 0.1 second. Find the frequency and time period of the wave.

A wave passes over a fixed point in space. If 20 compressions and 20 rarefaction pass the point in 0.1 s, find the frequency and time period of the wave.

Solve the following example: A sound wave has wavelength 0.85 m in air and 0.9 m in a gas. The speed of sound in air is 340 m//s . Find the frequency of sound and the speed of sound in the gas.

Answer the following What is the relation between frequency and time period of a sound wave?

Solve the following example: A sound wave has wavelength 0.86 m and speed 344 m//s in air. If its wavelength in a gas in 0.8 m, Find the speed of sound of sound in the gas.

A sound wave is passing through air column in the form of compression and rarefaction . In consecutive compressions and rarefactions,

Solve the following example: If the time period of a wave if 0.004s, find the frequency of the wave.

Solve the following example: A sound wave having certain frequency travels with a speed of 336 m//s and wavelength 3 cm. Calculate the frequency. Will it be audible?

Fill in the blanks : The total number of compressions and rarefactions produced per second in a sound wave is 1000. The frequency of the sound wave is ………………. .

Solve the following example: A person standing between two hills fired a gun and heard the first echo after 0.5 s and the second echo after 0.9 s. Find the distance between two hills. (speed of sound in air =340 m//s )

A progressive wave travels on a stretched string. A particle on this string takes 4.0 ms to move from its mean position to one of its extreme positions. The distance between two consecutive points on thew streing which are at their mean positions (at a certain time instant ) is 2.0 cm . Find the frequency , wavelength and speed of the wave.
