Question

Which ray diagram correctly illustrates what happens when light is incident from the air onto a flat glass surface? The dotted line represents the normal.

Answer 1

When light incident at angle more than critical angle then whole beam of light will get reflected at same angle into the same medium

So correct answer is

Option D

Step-by-step explanation:

Critical angle is the maximum angle of incidence for which light shows the phenomenon of refraction of light

Here light bends at 90 degree angle when light incident at critical angle

Now if the incident light is more than the critical angle then light will follow the rules of reflection and all light rays will get reflected at same angle as that of angle of incidence

So here we can say that correct answer is

Option D
