Answer 1

Answer:

The speed of light in diamond is 1.24 x 108 m/s.

Answer 2

Answer:

Speed of light in diamond is

$1.24 \times {10}^{8} m {s}^{ - 1}$

Explanation:

Refractive index of a medium is defined as the ratio of speed of light in vacuum(c) and speed of light in that medium(v)

$\eta \: = \frac{c}{v}$

$2.42 = \frac{3 \times {10}^{8} }{v}$

$v = \frac{3 \times {10}^{8} }{2.42}$

$v = 1.24 \times {10}^{8} m {s}^{ - 1}$
