Question

state and explain einstein's photoelectric equation​

Answer 1

Answer:

Explanation:

Einstein's photoelectric equation is given as, The energy of the incident photon is equal to the sum of the maximum kinetic energy of an electron and the work function. ... As the intensity increases, the number of photons striking the metal surface at a unit time increases. So the number of ejected electrons increases.

Answer 2

(explanation is in the attachment).

photonic when striking the metallic surface it releases some energy that must have minimum energy to send electrons out of the metallic surface called threshold. if the energy which is emitted by the proton is absorbed by electrons then the energy is being divided into 2 part.

• work function. ( energy which helps to send the electrons out of the metallic surface).
• kinetic energy. ( energy which is used by the electrons after coming out of the metallic surface ) .

from these two only the photoelectric equation came.

energy is being divided into two parts

E = work function + kinetic energy
