Which phenomena proves the particle nature of photon?
- A Interference
- B diffraction
- C polarisation
- D Photo electric effect
Answer & Solution
Correct Answer
(D) Photo electric effect
Step-by-step Solution
Detailed explanation
The photoelectric effect proves the particle nature of light because it shows that light interacts with matter as discrete packets of energy called photons. Phenomena like interference, diffraction, and polarisation are all evidence of the wave nature of light. D) Photo electric…

- Which of the following statements are correct?
(A) The current under reverse bias is essentially voltage dependent on a critical reverse bias voltage.
(B) The diode gets destroyed due to overheating if the forward or reverse current exceeds the rated value.
(C) In forward bias measurement, we use a milliammeter since the expected current is large, while a microammeter is used in reverse bias to measure the current.
(D) The drift current is of the order of a few \( \mu \)A
