Demo Title: Thick Lenses - Cylindrical Lenses
Condition: Good
Principle: Thick Lenses
Area of Study: Optics
Equipment:
Plastic Cylindrical Lenses, Titanium Oxide Sheet, and Choice Oxide Glass Lamp Sheet.
Procedure:
Place the cylindrical lens over the "titanium oxide" or "choice oxide glass lamp" words. As you raise the lens away from the sheet the non-symmetrical letters will invert top to bottom.
The large acrylic cylinders and the "One Eyed Jacks" from the deck of cards can be used together. The Jack will face the normal way when held against the acrylic rod but will about face 180 degrees when slowly moved away from the cylinder.
Note that when the Plexiglas cylinders are held horizontally over the words the inversion is top to bottom. When the cylinder is held vertically over the words the inversion is side to side or left to right.
