Question

The values of refractive index of some
materials are given below
kerosene. 1.44, water - 1.33, air - 1.0003,
benzene - 1.5
The arrangement of materials in the
increases order of velocity of light in
them
1
Kerosene, water, air and benzene
2
Kerosene, water, benzene and air
3
Benzene, kerosene, water and air
4 Air, water, kerosene and benzene
​

Answer 1

3) BENZENE , KEROSENE, WATER AND AIR

Answer 2

Answer:

point 3 is the correct answer because velocity of light increase as the refractive index decreases and speed of light is fastest in air
