For light of wavelength 589 nm, calculate the critical angles for the following substances when surrounded by a substrance with an index of refraction of 1.435: (a) fused quartz 79.81º 1.53º 83.76º 1.39º (b) polystyrene 1.39º 74.38º 79.54º 1.39º (c) sodium chloride 68.34º 62.67º 1.39º 1.32º
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.
