Question

assertion:- light traveling from air into a glass slab bends away from the normal. reason: light moves faster in air than glass slab​

Answer 1

Answer:

this is because when light travels from a rarer medium that is air to a denser medium that is glass slab it bends towards the normal thus the assertion is correct. And as air has less refractive index than the glass slab thus the light ray moves faster in air that glass slab thus the reason is absolutely correct.
