Question

There are two light sources A and B. The intensity of source A is more than that of source B. The frequency of light emitted by source B is higher than that emitted by source A. The photoelectric current obtained will be more from source

• A. B
• B. A
• C. Same from A and B
• D. None of these

Answer 1

Answer: (B)

A

The intensity of photoelectron depends on the intensity of the incident radiation. Since, the intensity of source A is more than that of source B. The photoelectric current obtained will be more from source A.

So, the answer is option (B).
