2 a piece of special flat glass that you can look into in order to see yourself or what is behind you

3 Light enters a water droplet, slowing down and bending as it goes from air to denser water. The light reflects off the inside of the droplet, separating into its component wavelengths--or colors. When light exits the droplet, it makes a rainbow.

4 There are two main types of lenses, known as convex (or converging) and concave (or diverging).

5 Lateral inversion is a phenomenon in which left appears to be right and vice versa. It is due to direction that light follows when it strikes a reflecting surface, generally a mirror.
