Concept introduction:
The photoelectric effect takes place when a certain frequency of strikes on a metal surface and electrons eject from it. There is dual nature of light. It has a wave as well as particle like properties.
Answer to Problem 37A
Phenomenon in which photoelectrons are emitted from metals surface is termed as photoelectric effect.
Explanation of Solution
The photoelectric effect takes place when a certain frequency of strikes on a metal surface and electrons eject from it. In photoelectric effect, electrons are called photoelectron. From the surface of the metals, the photoelectrons are released when light of a certain frequency or higher than that strikes on it.
