A
7.5cm
B
10.0cm
C
13.3cm
D
6.87cm

Correct Option: C
The relationship between real depth (actual depth) and apparent depth is given by the refractive index formula:
Refractive index (n) = Real depth / Apparent depth
We are given:
- Apparent depth = 10 cm
- Refractive index of water (n) = 1.33
We need to find the real depth. Rearranging the formula: Real depth = Refractive index × Apparent depth Real depth = 1.33 × 10 cm Real depth = 13.3 cm
