Code Number: 5N30.10
Demo Title: Glass, Water, & CS2 Prisms
Condition: Good
Principle: Dispersion of Light & Electromagnetic Radiation
Area of Study: Electricity & Magnetism
Equipment:
White light projector with 1000 watt bulb, Prisms or Gratings, Carbon Disulfide Prism.
Procedure:
There are 2 white light projectors. The one with only one cord is used for this demo. The one with two cords is for the Wien's law demos so that you may vary the light intensity and not ruin the fan motor.
Fill the hollow prism with the desired liquid or the desired combination of liquids. Observe the different amounts of dispersion. Use of carbon disulfide as the liquid is discouraged due to its hazardous environmental properties.
