Light travels in the form of photons. Identify the correct statements
(A) Photons travel with the velocity of light in vacuum.
(B) The rest mass of photons is taken as zero.
(C) Photons have energy which depends on frequency.
(D) Photons have a momentum inversely dependent on frequency.
Choose the correct answer from the options given below.
- A (A), (B), (C), and (D)
- B (A), (C), and (D) only
- C (A), (B) and (C) only
- D (B), (C) and (D) only
Answer & Solution
Correct Answer
(C) (A), (B) and (C) only
Step-by-step Solution
Detailed explanation
Statements (A), (B), and (C) are correct. Statement (D) is incorrect because momentum \(p = \frac{hf}{c}\) is directly proportional to frequency. Correct Answer: (A), (B) and (C) only
