Question

Refractive Index of glass with respect to air is 1:5 and refractive index of water with respect to air is 4/3 what will be refractive index of glass with respect to water
​

Answer 1

Answer:

Air is the invisible mixture of gases that surrounds the Earth. Air contains important substances, such as oxygen and nitrogen, that most species need to survive.

Answer 2

Explanation:

Refractive index is defined as the ratio of the speed of light in a vacuum to its speed in a specific medium.

Let us consider

Refractive index of air = Ra

Refractive index of glass = Rg

Refractive index of water = Rw

The refractive index of glass with respect to water is given as,

Rgw = Rg/Rw

9/8 = Rg/Rw……………………………..(1)

The refractive index of glass with respect to air is

Rga = Rg/Ra……………………………..(2)

The refractive index of water with respect to air is

Rwa = Rw/Ra……………………………..(3)

Substitute the value of (1), (2) in (3) we get

Rwa = 4/3

The refractive index of water with respect to air is 4/3.
