JEE Main 2025 — Dual Nature of Matter Question with Solution
JEE Main 2025 (4 Apr Shift 1)
Question
Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason
Assertion A: In photoelectric effect, on increasing the intensity of incident light the stopping potential increases.
Reason R : Increase in intensity of light increases the rate of photoelectrons emitted, provided the frequency of incident light is greater than threshold frequency.
In the light of the above statements, choose the correct answer from the options given below

Show full solutionCorrect option: B
Correct answer
B is false but is true
Step-by-step explanation
so stopping potential doesn't depend on Intensity
On increasing intensity no. of photons per sec. increases so the no. of electrons.
