Question

State the laws of photoelectric emission.

Answer 1

Answer:

Laws of Photoelectric Emission

Laws of Photoelectric EmissionThe emission of electrons from the surface of the metal can only be done when the sufficient amount of energy incident on their surface. The number of electrons emitted per second is directly proportional to the amount of light incident on the surface.

Answer 2

$\huge\colorbox{Limegreen}{Answer}$

state the laws of photoelectric emission

➡the stopping potential is directly proportional to the frequency of radiation but is independent of its intensity.

➡the photoelectric emission is an instantaneous process .the time lag between the incident radiation and the emission of photoelectrons is very small even less than ten to the power minus eight seconds.
