This ingenious LED Array provides a fun, eye-catching demonstration of how colors affect wavelengths. A major improvement over using color filters with a "white" showcase bulb, students can easily observe color diffraction from their seats and actually compare the diffraction patterns for each color, at the same time! Invaluable for determining the frequencies of the various colors, the LED Array features 11 vertically mounted lights ranging from deep red to violet, plus white. The eleven different color LEDs are mounted in a 12-inch metal tube. Colors and wavelengths are marked on the tube. And, the array is powered by a transformer that plugs into a standard 110-volt outlet. A rotary switch lets you display each color individually or all 11 simultaneously. You can switch on the LED's separately.
