2
3
4

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
(i) a medium pair so that light speeds up when it goes from one of these medium to another.
(ii) a medium pair so that light slows down when it goes from one of these medium to another.
Answers
Explanation:
(i) Crown glass to water
When a ray of light travels from denser medium to rarer medium, the speed of light increases. By saying that, it means that the speed increases when the ray of light travels from a medium having a higher refractive index to the medium having a lower refractive index. Here, the medium pair is crown glass to water.
(ii) Water to diamond.
When a ray of light travels from rarer medium to denser medium, the speed of light decreases. By saying that, it means that the speed decreases when the ray of light travels from a medium having a lower refractive index to the medium having a higher refractive index. Here, the medium pair is water to diamond.
