Question

the speed of light in a transparent medium is 1.8 into 10 power 8 m s find the respective index of that medium​

Answer 1

This is the answer. If you have any other doubt hit me up.

Answer 2

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
