Question

1. when light is going from a dense medium to a less dense medium, how is it bent?

away from the reflecting surface

towards the normal line

with the normal line

away from the normal line

Explanation:

This question is about the refraction of light. When light travels from a denser medium to a less dense medium, according to the law of refraction (Snell's Law), the light ray bends away from the normal line because the speed of light increases in the less dense medium, causing the direction to change such that it deviates from the normal (the perpendicular line to the surface at the point of incidence). The other options are incorrect: "away from the reflecting surface" is not related to refraction's normal - based bending; "towards the normal line" happens when light goes from less dense to denser medium; "with the normal line" is not a correct description of refraction bending.

Answer:

D. away from the normal line
