Webb8 nov. 2024 · Example 4.5.1. You have a machine that grinds glass surfaces to a certain specified radius. You use it to make a double-convex lens out of a special glass with high index of refraction equal to 2.75. You then use it to make a double-concave lens out of a different type of glass with index of refraction equal to 1.32. Webb31 dec. 2024 · Lenses work by bending (refracting) light beams. The bending happens when light enters the glass (passing from the air into the glass) and when it leaves again (passing from the glass back into the air).
