Define threshold frequency

Define the term "threshold freq uence", in the context of photolelectric emission.

(a) Define the terms , (i) threshold frequency and (ii) stopping potential in photoelectric effect. (b) Plot a graph of photocurrent versus anode potential for a radiation of frequency v and intensities I_1 and I_2 . (I_1 lt I_2) .

At frequencies of the incident radiation above the threshold frequency, the photoelectric current in a photoelectric

Assertion : The threshold frequency of photoelectric effect supports the particle nature of sunlight . Reason : If frequency of incident light is less than the threshold frequency , electrons are not emitted from metal surface.
