Question

the absolute refractive index of two media A and B are 2 and 1.5 respectively if the speed of light in medium B is 2 speed of light in medium A

​

Answer 1

Explanation:

$\gamma = \frac{c}{v}$

$c = v \times \gamma$

$c = 2 \times {10}^{8} \times 1.5$

$c = 3.0 \times {10}^{8} m {s}^{ - 1}$

$speed \: of \: light \: of \: medium \: \: a$

$v = \frac{c}{ \gamma }$

$v = 3.0 \times {10}^{8} \div 2 =$

$v = 1.5 \times {10}^{ - 8} \: \: \: \: \: answer$
