A green laser emits a beam of wavelength 532 light nm in the air. The wavenumber k is : Select one : a) 1.880 x 106 rad m-1 b) 1.067 x 107 rad m-1 c)1.181 x 107 rad m-1 d) 6.701 x 107rad m-1
Compton effect
The incoming photons' energy must be in the range of an X-ray frequency to generate the Compton effect. The electron does not lose enough energy that reduces the wavelength of scattered photons towards the visible spectrum. As a result, with visible lights, the Compton effect is missing.
Recoil Velocity
The amount of backward thrust or force experienced by a person when he/she shoots a gun in the forward direction is called recoil velocity. This phenomenon always follows the law of conservation of linear momentum.
