Options
- A. A
- B. B
- C. C
- D. D
Answer
A. A
Step-by-step solution
The energy of a photon is given by the relation: E = hc For the two radiations, the energies are E_1 = hc _1 and E_2 = hc _2 . The ratio of their energies is: E_1 E_2 = _2 _1 Substituting the given values _1 = 2000 and _2 = 6000: E_1 E_2 = 6000 2000 = 3 Answer: 3
