6F10.23 - Colors - Additive and Subtractive Primaries

Code Number:
6F10.23
Demo Title:
Colors - Additive and Subtractive Primaries
Condition:
Excellent
Principle:
Primary and Secondary Colors
Area of Study:
Optics
Equipment:
Diffraction Grating and Special Transparency Plate with Slit and Slat.
Procedure:

Put the diffraction grating on the head of the overhead projector.  When you put the special transparency plate on the overhead and turn it on you will have a spectrum of the primary colors on the top and the secondary colors directly underneath.
