Answer 1

Answer:

answer ))))) a) normal

b) optical denser

Answer 2

Answer:

(a) perpendicular to the plane

(b) Refraction

Explanation:

(a) Light traveling along the line perpendicular to the plane does not refract. If a light enters from one medium to the other medium along a line perpendicular to the second medium, the light rays don't refract.

(b) Lights bent when it flows from water into the air and we call this process refraction. When light from one medium it bent either away from the normal or towards the normal.
