The current increases with intensity but reaches a saturation level for large values of AV. Current At voltages equal to or more negative than -AV,, the High intensity current is zero. Low intensity Applied voltage Figure 39.10 Photoelectric cur- rent versus applied potential dif- ference for two light intensities. -AV, *Photoelectrons are not different from other electrons. They are given this name solely because of their ejection from a metal by light in the photoelectric effect.
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.
Consider one of the curves as shown. Suppose the intensity of the incident light is held fixed but its frequency is increased. Does the stopping potential as shown (a) remain fixed, (b) move to the right, or (c) move to the left?
