State a condition for no refraction of light entering from one medium to another.

When light passes from one medium to another, refraction does not happen under any one of the given conditions:

• If the ray is incident normally, then Angle of incidence = Angle of refraction = 0. So, there will not be any refraction
• If both media have the same refractive index, then also refraction will not occur.
