							yes mass is necessary for the momentum of any body.because in the expression of momentum=m*v
momentum of a wave is given by the expression p = \hbar k
transfer of momentum to the refarcted wave by the incident wave is called momentum transfer.
often momentum transfer is given by Q =  k_f - k_i
it is related to the wavelength k = 2\pi / \lambda.
