Question

When light enters from one medium to another, the condition for no refraction of
high
a) Light incident normally
b) Equal Refractive index of two media
c) Light incident with an angle 0°
d) Light incident with an angles 45°
​

Answer 1

Explanation:

There will be no refraction of light if the light travels in medium with exact same refractive index, for example there are two mediums A & B, light ray enters medium A & then medium B, there will be no change in the path of light ray if the refractive index of medium A is equal to refractive index of medium B

Answer 2

Answer:

C is the correct answer
