Dear tandrila


 When  a high-energy photon colliding with a target, which releases loosely bound electrons from the outer shell of the atom or molecule. The scattered radiation experiences a wavelength shift ,this is known as comton effect  ,which cannot be explained in terms of classical wave theory, thus lending support to Einstein's photon theory.


for example light is made up of particles (photons), and that photons have momentum, can be seen when a photon with energy hf collides with a stationary electron. Some of the energy and momentum is transferred to the electron , both energy and momentum are conserved in this elastic collision. After the collision the photon has energy hf/ and the electron has acquired a kinetic energy K.


 Conservation of energy: hf = hf' + K


 


Combining this with the momentum conservation equations, it can be shown that the wavelength of the outgoing photon is related to the wavelength of the incident photon by the equation:


Dl = l/ - l = (h/mec) (1 - cosq)
