Explanation:
When monochromatic radiation is incident on a completely opaque medium and 50% of the radiation is absorbed, the remaining 50% can only be reflected or transmitted. Let's analyze the given statements:
P) 50% of the incident radiation is reflected:
This statement is not correct because if 50% of the radiation is absorbed, there can't be 50% reflection. The sum of reflection and absorption cannot be more than 100%. Therefore, statement P is incorrect.
Q) 25% of the incident radiation is reflected:
This statement is correct. If 50% of the radiation is absorbed, then the remaining 50% can be divided equally between reflection and transmission. Therefore, statement Q is correct.
R) 25% of the incident radiation is transmitted:
This statement is correct. If 50% of the radiation is absorbed, then the remaining 50% can be divided equally between reflection and transmission. Therefore, statement R is correct.
S) No incident radiation is transmitted:
This statement is not correct. As mentioned earlier, if 50% of the radiation is absorbed, then the remaining 50% can be divided equally between reflection and transmission. Therefore, statement S is incorrect.
Therefore, the correct statements are Q (25% of the incident radiation is reflected) and R (25% of the incident radiation is transmitted). Hence, the correct answer is option A) P and S only.
