Question

9. Light ray travels from one medium to another with the same refractive index in case of glass slab a) the light rays bends less b) the light rays bends more c) bending of light does not occur d) total internal reflection occurs​

Answer 1

When light falls perpendicularly or normally on the surface of a glass slab, it goes straight. There is no bending of ray of light on entering the glass slab or coming out of it. In this case angle of incidence and angle of refraction is zero.
