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 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.

If the period of a wave is 2 times 10^-3 s, find the frequency of the wave.

Questions based on paragraph : Sound is propagated in a material medium in the form of compression and rarefactions. One compression and one rarefaction together form one cycle of the sound wave. The number of cycles produced per second is called as frequency. A tuning fork is a two-pronged device which vibrates to produce sound when struck. The frequency of a tuning fork is decided by the dimensions of the prong and the material used for making the fork. When these sound waves reach ears of listener, his ear-drum vibrates. Accordingly specific signals are conveyed to the brain and the listener gets a sense of hearing sound. : If a tuning fork has a frequency of 546 Hz, then how many times will it vibrate in a second?

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

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.

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

If the wavelength of a certain wave of light is 2.0 xx 10^3 cm. What is the frequency of this wave?

Find the equation of the curve passing through the point (0,1) if the slope of the tangent of the curve at each of it's point is sum of the abscissa and the product of the abscissa and the ordinate of the point.

A wave travelling along the x-axis is described by the equation y(x, t) = 0.005 cos ( alpha x - betat ). If the wavelength and the time period of the wave are 0.08 m and 2.0 s, respectively, then a and p in appropriate units are
