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
