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.
