Compare diffraction patterns from multiple wavelengths at once

This ingenious LED Array delivers a fun, eye-catching way to demonstrate color, wavelength, and diffraction with clarity students can see from anywhere in the room. A major improvement over using color filters with a white light source, this system allows students to directly compare diffraction patterns from different colors at the same time—making abstract wavelength differences immediately visible and measurable.

Why Teachers Love the LED Array

Clear, large-scale demonstrations: Students can easily observe diffraction patterns from their seats.
Direct color comparison: View multiple wavelengths individually or simultaneously for side-by-side analysis.
Improved accuracy: Eliminates ambiguity introduced by color filters and white bulbs.
Durable classroom design: 12-inch metal tube with clearly labeled colors and wavelengths.
Simple operation: Powered by a standard outlet with intuitive controls.

How the LED Array Works

Multiple light sources: The array contains 11 vertically mounted LEDs ranging from deep red to violet, plus white.
Selectable output: A rotary switch allows you to illuminate individual colors or all LEDs at once.
Diffraction ready: When used with a diffraction grating, each LED produces a distinct diffraction pattern.
Wavelength comparison: Students compare spacing between diffraction maxima to determine relative wavelengths and frequencies.
Plug-and-play power: The array is powered by a transformer that plugs into a standard 110 V outlet.

By making wavelength differences visible and comparable in real time, the LED Array turns color and diffraction into a vivid, accessible learning experience.
