WARD’S Light Waves Explorations Lab Activity |
A New Way to Look at Light |
Explore the wave properties of light, using new style holographic diffraction gratings, and two different types of patented diffraction goggles. The spectrum of a light emitting diode that shows completely white, as well as the spectra of three different colored L.E.D.s can be examined. The activity includes enough connecting leads and battery holders for two setups, as well as teacher notes and student copymasters with more than six investigations. Two AA batteries per setup, required, are available separately.
