RE-NEET 2026 Physics Refraction and Apparent Depth MCQ Question
Type: MCQ-numerical-Medium-Class 12
Consider three media P, Q and R with refractive indices 1, 1.25, and 1.5, respectively. The medium Q having a thickness of 5 cm is placed between extended media P and R as shown in the figure. An object O is placed at the center of medium Q. If viewed from medium P near the normal direction, the apparent depth of O is h₁. For similar observation from medium R, the apparent depth is h₂. The value of |h₁−h₂|, in cm, is:
A
1
B
2
C
3
D
0
Correct Answer
Option B
Detailed Explanation
The apparent depth is given by the formula h = real depth / refractive index. Calculating for both media, |h₁−h₂| = |5/1.25 - 5/1.5| = 2 cm.
