Answer:

Refractive index = Speed of light in vaccum / Speed of light in medium

n = c / v

v = c / n

= (3 × 10^8 m/s) / 1.8

= 1.67 × 10^8 m/s

Speed of light in given transparent medium is 1.67 × 10^8 m/s

Answer:

Answer

The refractive index is given by

n=c/v

Where n is the refractive index

c is the speed of light in vacuum

v is the speed of light in that medium

It is given that speed of light in a medium(v)is1.8∗1000=1.8∗103m/s

Speed of light in vacuum=3∗103m/sec

n=3∗103/1.8∗103

n=3/1.8

   =1.6666

   =1.67
