Question

With reference to photoelectric effect define the terms work function, threshold frequency and stopping potential. ​

Answer 1

Explanation:

Threshold frequency is defined as the minimum frequency of incident light which can cause photo electric emission i.e. this frequency is just able to eject electrons with out giving them additional energy. It is denoted by . WORK FUNCTION.

Answer 2

Explanation:

I think this effect work in plants toward the sun light
