Question Question 20
A ray of light starting from the air passes through medium A of refractive index 1.50, enters medium B of refractive index 1.33 and finally enters medium C of refractive index 2.42. If this ray emerges out in the air from C, then for which of the following pairs of media the bending of light is least?
- air-A
- A-B
- B-C
- C-air
A-B
Reason — The bending of light is least when the refractive index change is least. When light is travelling from medium A to medium B, the change in refractive index is from 1.50 to 1.33 which is the least in this case. Hence, the bending of light is also the least for A-B.
