Chang) Do you ever look at light through a transparent glass and see a small rainbow? No need to be a physicist to understand Snell's law (also known as Descartes' law, the Snell–Descartes law, and the law of refraction), a formula used to describe the relationship between the angles of incidence and refraction, when referring to light or other waves passing through a boundary between two different isotropic media, such as water and glass. Specifically, the law says that the ratio of the sines of the angles of incidence and of refraction is a constant that depends on the media. Educational, scientific humor gifts for all who know about the law of refraction!<br /> <br /> <div style="text-align:center;line-height:150%"><a
