Question

what are wavelength,frequency ,time period and amplitude of a sound wave

Answer 1

wave length:- the distance between two successive crests of a wave, especially points in a sound wave or electromagnetic wave

time period - it is a time needed for 1 complete cycle of vibration to pass a given point..

amplitude - the maximum displacement or distance moved by a point on A vibrating body or wave measured from the equilibrium position it is equal to 1 half the length of the vibration part

Answer 2

wavelength - the minimum distance in which a wave repeat itself is called wavelength. It is denoted by Greek word lambda . it's SI unit is metre.

frequency - the number of complete waves that are produce in one second is called frequency. Its SI unit is Htz(hertz)

time period - the time required to complete one wave is called time period.

amplitude - the maximum displacement of particles of wave from the line of zero disturbance Is called amplitude.
