You take a picture of a rainbow with aninfrared camera, and your friend takes a picture at the same timewith visible light. (a) Is the height of the rainbow in the infraredpicture greater than, less than, or the same as the height of therainbow in the visible-light picture? (b) Choose the best explanation from among the following:I. The height will be greater because the top of a rainbow is red,and so infrared light would be even higher.II. The height will be less because infrared light is below the visible spectrum.III. A rainbow is the same whether seen in visible light or infrared; therefore the height is the same
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.
