Question

Q. 3. Define :
(a) Threshold frequency
(b) Photoelectric work function
ta
​

Answer 1

Answer:

Threshold Frequency: Thethreshold frequency is thatminimum frequency of light below which the photoelectrons do not emit.Work function: The least energy which can eject the electrons from the surface of the metal

Answer 2

Explanation:

threshold frequency: the minimum frequency of radiation for which photoelectrons are emmitted form material is called threshold frequency.

in simple words minimum frequency required for photoelectric effect to occour.

work function: minimum energy required to free elecron from a surface of material is called as work function
