Assertion (A) Electromagnetic waves exert pressure, called radiation pressure.
Reason (R) This is because they carry energy.
- A Both \(A\) and \(R\) are true and \(R\) is a correct explanation for \(\mathrm{A}\).
- B Both \(A\) and \(R\) are true but \(R\) is not a correct explanation for \(\mathrm{A}\).
- C \(A\) is true but \(R\) is false.
- D \(A\) is false but \(R\) is true.
Answer & Solution
Correct Answer
(B) Both \(A\) and \(R\) are true but \(R\) is not a correct explanation for \(\mathrm{A}\).
Step-by-step Solution
Detailed explanation
Electromagnetic waves (EMW) exerts pressure, called radiation pressure. In perfect reflecting waves, \(p=2 I / C\) In perfect absorbing waves, \(p=I / C\) So, Assertion is true. EMW exert pressure on the surface because they carry energy also. Therefore reason is also true. But,…
