MHT CET 2024 Physics question
A parallel beam of light of intensity is incident on a glass plate, 25% of light is reflected by upper surface and 50% of light is reflected from lower surface. The ratio of maximum intensity interference region of reflected rays is
Answer: (A)
Solution
The ray reflected from the upper surface has intensity of . The remaining () enters the glass and of this is reflected at the lower surface, so . Interference gives $ =
