About this unit

When light travels from one medium to another (like air to glass, or glass to water), it does three things. Some of it bounces off, some of it goes through, and the rest of it is absorbed. In this chapter, we will explore the first two. We will explore what rules govern them, their technical names and then apply these rules to study the beautiful world of curved mirrors and lenses.
