For a perfect black body, the absorption coefficient is
- A \(a=1\)
- B \(a < 1\)
- C \(a>1\)
- D \(a=0\)
Answer & Solution
Correct Answer
(A) \(a=1\)
Step-by-step Solution
Detailed explanation
A perfectly black body absorbs \(100 \%\) of radiation incident on it, hence absorption coefficient \(\left(a_r\right)\) is given as…
