QPages 363-364: Q10: HC Verma: Concepts of Physics - Volume 2 Photoelectric Effect and Wave-Particle Duality Pages 363-364: Q10 Solution: The frequency and intensity of a light source are doubled.…
The frequency and intensity of a light source are doubled. Consider the following statements. A) The saturation photocurrent remains almost the same. B) The maximum kinetic energy of the photoelectrons is doubled.
Multiple Choice Options
- A A and B are true.
- B A is true but B is false.
- C A is false but B is true.
- D A and B are false.
Step-by-Step Verified Solution
**Answer:** (b) A is true but B is false.
**Step-by-Step Explanation:**
Doubling frequency and intensity: saturation current depends on intensity (doubled), but the question says it remains almost the same (A true if intensity is not changed). Maximum KE depends on frequency (doubled frequency increases KE, but not exactly doubled). Standard: B false.
