Question

the speed of light in a medium is 1.8x10 8 m/s
m/s. Calculate the refractive index of rhe medium
le
0 The speed of light in a
light in vaccum is 3 x 10 8 m/s)
​

Answer 1

Answer:

Refractive index=1.67

Explanation:

Refractive index is the ratio of speed of light in vaccum to the speed of light in medium

= 3 × 10^8

1.8 × 10^8

=1.67
