The following table gives the refractive indices of a few media: 1 2 3 4 5 Medium: Water Crown glass Rock salt Ruby Diamond Refractive index: 1 . 33 1 . 52 1 . 54 1 . 71 2 . 42 Use this table to give an example of a medium pair so that light speeds up when it goes from one of these medium to another.

When light ray travel from a medium of high refractive index to the medium of low refractive index it, speeds up. That means, the speed of light decreases as it enters a denser medium. From the given data one such example will be, light travelling from crown glass to water.

The following table gives the refractive indices of a few media: 1 2 3 4 5 Medium: Water Crown glass Rock salt Ruby Diamond Refractive index: 1 . 33 1 . 52 1 . 54 1 . 71 2 . 42 Use this table to give an example of: A medium pair so that light slows down when it goes from one of these medium to another.

When light ray travel from medium of low refractive index to the medium of high refractive index it slows down. This also means the speed of the light increases as it travels from a medium of high refractive index to a region of low refractive index. From the given data one such example will be light travelling from water to diamond.

Refractive indices of four media A , B , C and D are given below: Medium Refractive index A 1 . 33 B 1 . 44 C 1 . 52 D 1 . 65 In which of these four media is the speed of light (i) maximum, and (ii) minimum?

(i) The medium which has the lowest refractive index will have the maximum speed of light. Hence, the speed of light will be maximum in medium A. (ii) The medium which has the highest refractive index will have the minimum speed of light. Hence, the speed of light will be minimum in medium D.
