Question

When a ray is incident along the normal , what will be the angle of refraction while going from one transparent medium to another? ​

Answer 1

Answer:

As previously mentioned, in this case light rays are bent away from the normal of the interface between the media. At what is called the critical angle of incidence (Θ), the refracted rays make an angle of 90° with the normal—in other words, they just skim the boundary of the two media.
