Question

if a ray is incident normally on the surface separating two media passess undeviated what will be the value of angle of incidence and angle of refraction​

Answer 1

Answer:

4.2 Refraction from denser to rarer medium part ) (3) The ray of light incident normally on the sterface separating the two media, passes AO, undeviated (i.e., such a ray suffers no bending at the surface). Thus if angle of incidence Zi = 0°.
