Code Number: 6A20.10
Demo Title: Mirrors - Blackboard Optics - Curved Mirrors
Condition: Excellent
Principle: Reflection & Geometric Optics
Area of Study: Optics
Equipment:
Blackboard Optics Kit, 12 VDC Power Supply, and Dry Erase Blackboard on Wheels.
Procedure:
The blackboard optics unit is pretty self explanatory, however there is a pamphlet on its use with the unit and in the file. Do Not run the power supply for the light bulb over 12 volts.
Dry erase markers are in the drawer on the B.B Optics Unit.
