Question

Define threshold frequency and photoelectric work function.​

Answer 1

Threshold frequency is defined as the minimum frequency of light which causes electrons to be emitted from a metal Surface

The minimum energy required to eject an electron from the surface is called the photoelectric work function

Answer 2

To Define :

Threshold frequency and photoelectric work function .

Solution :

Threshold frequency is defined as the minimum frequency of photon required to eject an electron from the surface of metal .

Also , photoelectric work function is the minimum energy required by a photon to eject an electron form the surface of metal .

Also , work function and threshold frequency are related as :

$W_o=h \nu_o$

Therefore , this is the required solution .
