14. Every morning Elsa looks at her image in a shiny flat surface. Which statement below explains the behavior of light that allows Elsa'o see herself?
A. Light waves are absorbed by the surface of the object allowing Elsa to see
herself.
B. Light waves are reflected from the surface back into Elsa's eyes allowing her
to see herself.
C. Light waves are refracted by the surface of the object bending the light and
allowing Elsa to see herself.
D. Light waves are diffracted by the surface of the object creating shine that
allows Elsa to see herself

B

Explanation:

It's not (a) because light waves can only be absorbed by certain surfaces. Since the question doesn't specify a surface, we can assume that it wasn't a surface that can absorb light. It's not (c) because light bending is known is diffraction and not refraction. It's not (d) because in order for light to bend, there has to be something for it to bend around. If Else is staring directly into the surface, there's nothing for it to bend around. This leaves B as the only remaining answer.
