Question

What is photoelectric effect? Write Einstein’s photoelectric equation and use

it to explain: (i) independence of maximum energy of emitted photoelectrons

from the intensity of incident light. (ii) Existence of a threshold frequency for

the emission of photoelectrons..​

Answer 1

Answer:

photoelectric effect is a effect where a incident light of frequency greater that threshold frequency falls on the metal plate electrons are ejected from the plate

this is given by the photo electric equation

kEmax=hV-workfn(v is frequency and workfn=hv° where v° is threshold frequency and kE IS KINETIC ENERGY)

another point is emmison takes place when hv>workfn

THATS ITT
