Light travels in a straight line forever—that is, unless it encounters an object that absorbs, reflects, or transmits it. At the exhibit Light Island, you can see how light behaves after it's interacted with a lens, a curved mirror, or a straight mirror. Do light beams travel in parallel forever, or do they eventually come together? Senior Scientist Paul Doherty shows how Light Island works.
