Demonstrations are cataloged according to PIRA Bibliography

PLEASE REQUEST DEMOS WELL IN ADVANCE

Due to Physics Building renovations, the lead time to set up demo requests has increased due to the need to transport equipment across campus. Please be kind and let me know well ahead of time what you need.

Thin Lenses with Objects

Purpose:

To demonstrate the geometrical optics of thins lenses with 3D objects.

Procedure:

Light up 3 distinctly shaped light sources (long and tall, long and short and round) and set them up at the edge of the bench. Position the optical bench about 2 m away. Set up a lens in question in front of a ground glass screen and position a camera behind the screen. Demonstrate the usual geometrical optics things, formation of the various images, focal length of a lens, inversion of an image etc. etc.

Equipment:

10 inch single filament lamp
10 cm Lens and stand
20 cm Lens and stand
Ground Glass Screen
Round Filament Lamp
