SATHEE: Optics Question 712

Optics Question 712

Question: The index of refraction of diamond is 2.0, velocity of light in diamond in cm/second is approximately

[CPMT 1975; MNR 1987; UPSEAT 2000]

Options:

A) $6 \times 10^{10}$

B) $3.0 \times 10^{10}$

C) $2 \times 10^{10}$

D) $1.5 \times 10^{10}$

Show Answer

Answer:

Correct Answer: D

Solution:

$v = \frac{c}{μ} = \frac{3 \times 10^{8}}{2} = 1.5 \times 10^{8} m / s = 1.5 \times 10^{10} c m / s$
