Progressive wave with doubly periodic motion means.

Progressive Waves

Assertion : In a progressive wave motion, particle velocity is constant at all time. Reason : This is because density of medium is uniform throughout.

The maximum displacement of any particles either sides of mean position when a progressive wave is propagating through a medium is

Transverse progressive wave .

The equation of a plane progressive wave travelling along positive direction of x- axis is y=r sin [(2pit)/(T)-(2pix)/(lambda)] where y= displacement of particle at (x,t),r= amplitude of vibratio of particle, T= time period of wave motion, lambda= wavelength of wave , x= starting distance of wave from the origin. Velocity of wave, upsilon=vlambda=(lambda)/(T)= constant. Acceleration of wave, a=0 . Velocity of particle at time t=(dy)/(dt) Acceleration of particle at time t=(d^(2)y)/(dt^(2)) Time period of wave motion is
