MCQ
The refractive index of water is:
- A1.33
- B1.50
- C2.42
- D1.36
✓
Answer
- 1.33
Explanation:
Velocity of light in water = 225,563,010m/ s
Velocity of light in air = 300,000,000m/ s
$\text{Refractive index}=\frac{\text{Velocity of light in air}}{\text{Velocity of light in water}}$
$\text{Refractive index}=\frac{300,000,000}{225,563,010}$
$\text{Refractive index}=1.33$
