हिन्दीConsider three media \( P \), \( Q \) and \( R \) with refractive indices \( 1 \), \( 1.25 \), and \( 1.5 \), respectively. The medium \( Q \) having a thickness of \( 5\text{ cm} \) 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 \( h_1 \). For similar observation from medium \( R \), the apparent depth is \( h_2 \). The value of \( |h_1 - h_2| \), in \( \text{cm} \), is :
Correct answer · Option 1
0
Explanation
Apparent depth formula from each boundary accounts for successive refractions, leading to \( |h_1 - h_2| = 0 \) by symmetry or exact calculation.
