Question

Two mediums A and B with refractive index 1.33 and 1.50 are given. In which case is

1. bending of light more?

2. speed of light more. justify your answers.

Answer 1

bending of light will be more in the medium withmore refractiver index that is medium B with refractive index 1.5 and the speed of light will be more for which the rrefractive index is less that is medium A with refractive index 1.33 because when refractive index is less it is a rarer medium so speed of light is more

Answer 2

Bending is more in medium B and the speed of light is more in medium A.

Explanation:

• The refractive index of medium A and B are 1.33 and 1.50.
• The bending of light depends on the refractive index of the medium. The more the refractive index of a material the more is the bending.
• So, the medium having refractive index of 1.5 will bend more.
• The refractive index of the material is inversely proportional to the speed of light in that medium. So, more the refractive index, lesser will be the speed and vice versa.  

Hence, Bending is more in medium B and the speed of light is more in medium A.
