When Light Waves Collide

by: William C. Robertson, Ph.D.

Light doesn't always travel in straight lines. It can bend around corners, just like sound. When it does change direction like this, you end up with light waves that originated from different places coming together at one spot. This can lead to some really cool effects and pretty colors. You saw those colors when you looked through the diffraction grating that came with the book. You get to find out how that thing works in this chapter.
