Question

A ray of light travel through a compound medium of 3× 10⅞ and refract index of water w. r. t air is 1.33 and that if glass w. r. t water is 1.12. Calculate the velocity of light in glass.​

Answer 1

Answer:

1.34

Step-by-step explanation:

Refractive index of glycerine w.r.t. water =  

Absolute r.i. of water

Absolute r.i. of glass

​

 

or, 1.12=  

n  

water

​

 

1.5

≈1.34

Answer 2

Answer:

Refractive index of glycerine w.r.t. water =

Absolute r.i. of water

Absolute r.i. of glass

or, 1.12=

n

water

1.5

or, 1.12=

1.12

1.5

≈1.34
