Description
The LED array enables teachers to demonstrate color diffraction and the relationship between color and wavelength. This array has 11 separate LED light colors (violet, deep blue, blue, turquoise, bright green, green, yellow, orange, red, deep red, and white) that can be turned on individually or all at the same time with a rotary switch. Each LED bulb is identified by color and associated wavelength, which is printed on the 12″ metal tube. On/off switch is on the back. Uses a 110-V adapter (included).
