A New Optics First: The Anti Laser

Posted on May 1, 2011 by Buzz Putnam

You probably won't find this product in the Arbor Scientific catalog anytime soon, but it is definitely cool stuff! The Anti-Laser was demonstrated recently for the first time at Yale University. The fundamental concept of the Laser is that it is able to transmit "Coherent Light", which are monochromatic (one color) light waves that are [...]

Think red and green make brown? Only with paint and crayons! In color science, those colors of light make yellow. When I demonstrate that with the Color Mixing Spotlights, students discover there's no one answer for what color a strawberry is. The demo doesn't just give them a new way of seeing color, it shows them science as a new way of seeing their world.

One of the most common questions asked by students is “Why is the sky blue?” or “Why is the Sun yellow?” The answer is found by understanding color science concepts and some basics of color addition. Assuming that the Sun is “white” as viewed from space (no atmosphere) and that the three primary colors of light (red, blue and green in equal hues, saturation levels, etc) compose the white color that is observed.
