Electrons are emitted with kinetic energy \(T\) from a metal plate by an irradiation of light of intensity \(J\) and frequency v. Then, which of the following will be true?
- A \(T \propto J\)
- B \(T\) linearly increasing with \(v\)
- C \(T \propto\) lime of irradiation
- D Number of electrons emitted \(\propto J\)
Answer & Solution
Correct Answer
(D) Number of electrons emitted \(\propto J\)
Step-by-step Solution
Detailed explanation
In photoelectric effect, if the incident light had a frequency less than a minimum frequency \(v_{0}\), then no electrons are ejected regardless of the light's amplitude. This minimum frequency is also called the threshold frequency, and the value of \(v_{0}\) depends on the…
