Question

Is a denser or rarer nature relative or absolute? Arrange the following media in order of increasing denser nature.
The refractive indices of air, glass, kerosene and diamond are 1, 1.5, 1.44 and 2.42 respectively.

Answer 1

Explanation:

a) The refractive index of medium 2 with respect to medium 1 can be written in two ways. i)1n2

ii) n21

b) Denser are rarer is a relative term. We compare the density of different materials.

The increasing order of density is air, kerosene, glass, diamond.

Answer 2

Answer:

The increasing order of the refractive indices is  Air, kerosene, glass and diamond.

Explanation:

• A Denser medium is defined as when the speed of the light is relatively more it is called as optically rare medium.
• When a speed of the light in a medium is less it is called as optically denser medium.
• It is a substance with higher density and it is heavier in weight.
• The Denser are rarer and it is a relative term.
• The density is compared with the different materials rationally.

• The increasing order of density is:

Air, kerosene, glass and diamond.

Air:

An air is a invisible gaseous mixture that is surrounded by a mixture of hydrogen and oxygen.

The refractive indices of the air is 1.

Kerosene:

Kerosene is a light fuel which is obtained from the petroleum.

The refractive indices of the kerosene is 1.44

Glass:

A glass is a hard substance which is transparent and can made up with fusing sand.

The refractive indices of the Glass is 1.5

Diamond:

A diamond is stone which is colorless in the from of pure crystalline and it is harder in nature.

The refractive indices of the diamond is 2.42
