Demo Title: Holograph with Magnifier

Condition: Excellent

Principle: Images Produced by Wave Interference

Area of Study: Optics

Equipment:

Cole-Parmer Hologram, Holographic telephone pictures in frame, magnifier and pocket watch hologram.

Procedure:

The Cole-Parmer hologram shows a circuit board with a magnifier over the board. As you move your head over the board the magnifier moves with you.

The telephone hologram needs to be illuminated by a diffuse laser beam. Again, you will see a magnifier looking at the keys of a telephone. The magnifier will move as you move.

The magnifier over the pocket watch is just another good version of these holograms.
