2023-24 Chapter 22D "Refraction and Lenses"

Converging Lens

• ratio of the speed of light in a vacuum to the speed of light in a different medium

• when a light ray's angle of incidence exceeds a certain critical value when going into a medium with a lower index of refraction

• a transparent material that refracts light to produce a real or virtual image

• a lens that collects incoming rays of light an focuses them at a point

• a lens that spreads rays of light apart similar to what a convex mirror does

Light travels faster in medium A than in medium B. Which medium has a higher index of refraction?

• A

• B

• neither, light travels at a constant speed of light through all mediums
