In a completely opaque medium, if 50 percent of the incident monochromatic radiation is absorbed, which of the following statements are CORRECT?
- (P) 50 percent of the incident radiation is reflected
- (Q) 25 percent of the incident radiation is reflected
- (R) 25 percent of the incident radiation is transmitted
- (S) No incident radiation is transmitted
In a completely opaque medium, if 50 percent of the incident monochromatic radiation is absorbed, which of the following statements are CORRECT?
- (P) 50 percent of the incident radiation is reflected
- (Q) 25 percent of the incident radiation is reflected
- (R) 25 percent of the incident radiation is transmitted
- (S) No incident radiation is transmitted
Show Hint
- P and S only
- Q and R only
- P and Q only
- R and S only
The Correct Option is A
Solution and Explanation
- In a completely opaque medium, no radiation is transmitted (\( S \) is correct).
- Since 50 perceny is absorbed, the remaining 50 percent is reflected (\( P \) is correct).
Conclusion: The correct answer is option (A).
