Answer & Solution
Correct Answer
(A) (A), (B) and (C) only
Step-by-step Solution
Detailed explanation
(A), (B) and (C) only (A) Photographic plates are sensitive to infrared waves: Correct. While standard photographic film is primarily sensitive to visible light and UV, specially treated "infrared plates" or films are used in scientific and aerial photography to capture infrared…
