Question

State two condition for no refraction of light when entering from one medium to another

Answer 1

Answer:

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:

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.(orEqual refractive index of two media.)
• Light incident normally.
