Answer 1

When light travels from a slower medium to a faster medium at an angle, it moves towards the normal.

Step-by-step explanation:

When light travels from a slower medium to a faster medium at an angle, it bends towards the normal. The normal is an imaginary line perpendicular to the surface of the interface. So, in this case, the incident ray will move towards the normal.
