12 V AC/DC with full kit of slits and filters - Complete with instructions

The Diffraction Kit is a low cost and unique instrument to teach the principles of diffraction. The kit is self contained and housed in a small plastic box. A mono-filament lamp provides a line source of light and it is viewed through various single and double slit sets produced photographically and supplied in the kit. An adjustable slit is provided. A set of colour filters to observe different patterns of different colours is also provided. A simple scale is mounted behind the light source to measure the distances between the dark and light bands of light.
