ray bends away from normal when travelling from​

Answer 1

A ray bends away from normal when travelling from rarer medium to a denser medium.

Answer 2

Answer:

If light travels into a substance with a lower refractive index (such as from water into air) it speeds up. The light bends away from the normal line.

Explanation:

i.e. The light bends away from the normal when light travels from high refractive index (denser medium) to low refractive index (rarer medium).
