DESCRIPTION

Project narrow beam of light through prism onto screen to show spectrum.  Spectrum looks a lot better than the image taken by the digital camera above.

 

NOTES

 

The prism labeled 105-71-B-10 works nicely.  Adjust orientation for maximum dispersion.

Angle slide projector so spectrum falls on south screen.
