Question

light enters from air to medium x its speed in x is 2.5×10^8 find refractive index of medium​

Answer 1

Explanation:

According to Snell's Law,

Refractive index of a medium X=

v

c

where c is speed of light in air and v is speed of light in medium X.

So, Refractive Index of X=

1.5×10

8

3×10

8

=2

Answer 2

Answer:

Explanation:

0.8 mu
