Estimate the angular spread of a laser beam due todiffraction if the beam emerges through a 3.0-mm-diametermirror. Assume that λ = 694nm What would be the diameter of this beam if it struck (a) a satellite 340 km above the Earth, or (b) the Moon?
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.
