Question

6. Given below are the refractive indices of three media
Kerosene
Turpentine
Water
1.44
1.47
1.33
based on above data answer the following questions:
(i) In which of the three media is the speed of light slowest & why?
(ii ) In which of the three media is the speed of light fastest & why?
(iii) Select a pair of media such that a ray of light bends away from the normal as it passes from one
medium to another.
(iv) Select a pair of media such that a ray of light bends towards the normal as it passes from one
medium to another.​

Answer 1

Answer:

1. turpentine because refractive index is inversely proportional to speed of light.

2. water.

4.water.
