Question

18. Describe the activity to show refraction through the glass slab. State the laws of

refraction. Mention the behaviour of refracted ray when it passes through rare to denser

and denser to rare media.​

Answer 1

When light rays travelling through air enters glass slab, they get refracted and bend towards the normal. Now the direction of refracted ray changes again when it comes out of the glass slab into air. Since the ray of light I know travelling from denser medium to rarer medium, it bends away from the normal

Answer 2

Answer:

When light rays travelling through air enters glass slab, they get refracted and bend towards the normal. Now the direction of refracted ray changes again when it comes out of the glass slab into air. Since the ray of light I know travelling from denser medium to rarer medium, it bends away from the normal.
