Question

. Absolute refractive Index of some of material is tabulated below.
material:glass,kerosene,water
refractive:1.542, 1.44 , 1.33
diamond
2.42
i) In which of these does light travel slow and why?

ii) Arrange these materials in descending order of their optical densities.

iii) If a ray of light travels from glass to any of the above listed medium, then in which of

these media do the ray bends the most and why?​

Answer 1

1 diamond

2 water ,kerosene,glass,diamond.

3diamond becaomd high refractive index . diamond having higher refractive index,is optically denser than glass
