Question

Light enters from air into glass plate having refractive index 1.50. What is the speed of light in glass? ​

Answer 1

Explanation:

3×10^8

Hope it will help you

Answer 2

Answer:

The speed of light in glass is 2*10^8m/s.

$\large \underline{ \underline \mathfrak explanation - }$

We know that,

Refractive index of glass =$\huge \frac{speed \: of \: light \: in \: air}{speed \: of \: light \: in \: glass }$

$\huge \mathfrak{1.50 = \frac{3 \times {10}^{8} }{speed \: of \: light \: in \: glass} }$

Speed of light in glass =$\huge \ \frac{3 \times {10}^{8} }{1.50} \\ = 2 \times {10}^{8}$
