COMPTON’S EFFECT

When a beam of monochromatic X-Ray is made on a block of graphite and measured the wavelength of the scattered radiation at different scattering angles the scattered x-ray beam consist of two wavelength are with the same wavelength as that of the incident beams and was called unmodified radiation while the other with slightly higher wavelength which is known as modified radiation. This phenomenon known as Compton Effect and the change in wavelength is known as Compton Shift.



Let X-Ray photon collide with an electron at rest at 0. After collision they move in the direction as incident. 

Before Collision (While electron is at rest)



After Collision (While electron moves with velocity)

Laws of Conservation

Applying the principle of conservation of momentum along the direction of incidence
