PHYSICS - LIGHT
|COMPONENTS OF LIGHT - When the three primary
colors of light combine, the result is white light, and when the young
child casts his shadow on the wall and blocks one or two of the lights,
the lack of the other components cause the shadows to be in color. The
three primaries of light are Red, Green and Blue, hence the abbreviation
RGB. The three primaries of pigments are Cyan, Magenta and Yellow. A
black pigment is added in printing to enhance the image and hence the
Prototype for a children's museum exhibit.
|LIGHT TABLE - Here the visitor can experiment with lenses, mirrors, filters and other optical components to understand the nature of light. Children's Museum, Upton NY.|

|CRITICAL ANGLE - When light hits a clear medium of a different density (such as when going from air into water) it either goes through it or is reflected. Each medium has its critical angle determining how the light behaves in one of the two conditions. In the exhibit above a laser beam (left) shines on a mirror submerged in water, bounces from the bottom of the tank from a second mirror and is reflected again from a third mirror. Then, if the angle is correct it is directed into a hole from which the water escapes. Internal reflections inside that stream, cause the light beam to "bend" and follow the stream. (Far right, as it happens in fiber optics.) The visitor can adjust the angle of the first and third mirrors, and by doing so, cause the laser beam to either be reflected back from the surface inside the water, or to "escape" outside the tank.

|FIBER OPTICS - Hundreds of fiber optic strands
form the title of this exhibit. The visitor can rotate the color filter
wheel to change the light color that goes through the fibers. The
component in the box on the right, allows the visitor to create
different light paths using modular components.Liberty Science Center, NJ.
All exhibits on this page were designed and produced at Levy Design Studios in Portland, Oregon, USA.
