The Wavenumber k is : Select one : a) 1.880x106 rad m-1 b) 1.067 x 107 rad m-1 c) 1.181 x 107 rad m-1 d) 6.701 x 107 rad m-1 1B) For the same 532 laser above, the angular frequency ω is : a) 5.094 x 1014 rad s-1 b) 3.543 x 1015rad s-1 c) 2.978 x 1015rad s-1 d) 6.401x 1015 rad s-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.
