JEE Mains · Physics · STD 12 - 11. Dual nature of radiation and matter
From the photoelectric effect experiment, following observations are made. Identify which of these are correct \(A.\) The stopping potential depends only on the work function of the metal. \(B.\) The saturation current increases as the intensity of incident light increases. \(C.\) The maximum kinetic energy of a photo electron depends on the intensity of the incident light. \(D.\) Photoelectric effect can be explained using wave theory of light. Choose the correct answer from the options given below:
- A \(B, C\) only
- B \(A, C, D\) only
- C \(B\) only
- D \(A, B, D\) only
Answer & Solution
Correct Answer
(C) \(B\) only
Step-by-step Solution
Detailed explanation
\((A)\) Stopping potential depends on both frequency of light and work function. \((B)\) Saturation current \(\propto\) intensity of light \((C)\) Maximum \(KE\) depends on frequency \((D)\) Photoelectric effect is explained using particle theory
