Concept explainers

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.

39. Which of the following statements is true for the experimental findings on photoelectric effect? Within the limits of experimental accuracy there is not time interval between the arrival of light at the metallic surface and emission of photoelectrons. A bright light yield the same number of photoelectrons than a dim one at the same frequency but the electron energies are not the same. Higher frequency of light yields more photoelectrons at the same intensity of light incident on the metal surface. Both the intensity and frequency of light do not affect the number of photoelectrons produced at the metallic surface as well as the energy of the emerging photoelectrons.
