BITSAT Physics Question (2024) — Solution
Options
- A.
- B.
- C.
- D.
Answer
C.
Step-by-step solution
Given lights are of same wavelength and stopping potential is independent on intensity. Hence stopping potential will remain same. Intensity I _2 I _1, hence saturation current corresponding to I _2 will be greater than that corresponding to I _1.
