COMEDK · Physics · 12. Thermal Properties of Matter
Absorption coefficient of an open window is
- A \(1\)
- B \(0.25\)
- C zero
- D \(0.5\)
Answer & Solution
Correct Answer
(A) \(1\)
Step-by-step Solution
Detailed explanation
An open window is like a perfectly black body that absorbs completely the quantity being transferred, so its absorption coefficient is unity or \(1 .\)
