Question

the refractive index of glycerine is 1.46 what is the speed of light in glycerine if it's speed in air is 3× 1000000000m/s

Answer 1

if correct add me as brainist

Answer 2

hey mate.....☺️☺️☺️☺️✌️✌️✌️✌️✌️

Given:

refractive index of glycerine = 1.46

speed of light in air= 3× 10^8 m/s

Refractive index of glycerine = speed of light in air/speed of light in glycerine

1. 46 = 3× 10^8/ speed of light in glycerine

Speed of light in glycerine= 3× 10^8/1.46

= 2.053 × 10 ^8 m/s

Hence, the Speed of light in glycerine= 2.053 × 10 ^8 m/s
