Question

Photoelectric effect supports quantum nature of light because:

• A. There is a minimum frequency below which no photoelectrons are emitted
• B. The maximum kinetic energy of photoelectrons depends only on the frequency of light and not on its intensity
• C. Even when the metal surface is faintly illuminated the photoelectrons depends only on the frequency of light and not on its intensity
• D. Electric charge of the photoelectrons is quantized

Answer 1

Answer: (A), (B), (C)

Correct answer is (a) There is a minimum frequency below which no photoelectrons are emittedCorrect answer is (b) The maximum kinetic energy of photoelectrons depends only on the frequency of light and not on its intensityCorrect answer is (c) Even when the metal surface is faintly illuminated the photoelectrons depends only on the frequency of light and not on its intensity
