Solution

The correct option is C The photoelectric effect
When light or EM radiation of frequency greater than the threshold frequency of the metal falls on the surface of metal, then the photoelectrons are emitted and thus the process is called as the photoelectric effect.

Q. The green graph and the purple graph pictured below represent the photoelectric effect for two different metals (G and P).
If electromagnetic radiation of frequency

11 \times 10^{14} H z

strikes both metal surfaces, which of the following statements must be true?

When a high frequency electromagnetic radiation is incident on a metallic surface, electrons are emitted from the surface. Energy of emitted photoelectrons depends only on the frequency of incident electromagnetic radiation and the number of emitted electrons depends only on the intensity of incident light.

Einstein's photoelectric equation

[K_{m a x} = h ν - ϕ]

correctly explains the PE, where

ν =

frequency of incident light and

ϕ =

The slope of the graph shown in fig. [here h is the Planck's constant and e is the charge of an electron] is
