Question

The speed of light in two transparent media A and B are 2×10^8 m/sec and 2.25 × 10^8 m/sec. The refractive index of medium A with respect to medium B is equal to?

• A. 1.125
• B. 4.50
• C. 0.89
• D. 4.25

Answer 1

Answer:

A. 1.125

• The refractive index of medium A with respect to medium B is calculated as

• 2.25×10^8÷2×10^8=1.125
