Ophthalmic OpticsQuestion 3 of 100
Light traveling from a less dense medium into a more dense medium will do what?
a.Slow down and bend toward the normal
b.Speed up and bend away from the normal
c.Continue at the same speed
d.Stop completely
Explanation
When light enters a denser medium (higher index of refraction) it slows down and refracts toward the normal. This bending of light is the basis of how lenses focus rays.
