6B - Photometry
 |
6B 10.10 - Light Output as a Function of Input Power:
Demonstrates: The light output is dependent on voltage but not on amperage. Description: An auto light bulb is hooked to a variable power source, a voltmeter and an ammeter. |
 |
6B 10.20 - Inverse Square Law with Light:
Demonstrates: Inverse Square Law. Description: A light meter and a 25 W bulb are used to illustrate this law. |
 |
6B 10.30 - Point and Diffused Light Sources:
Demonstrates: Umbra and penumbra shadows. Description: Use a diffuse source and a point source. Project shadows of object on wall or screen to show umbra and penumbra. |
 |
6B 40.20 - Luminosity and Flux:
Demonstrates: Black body radiation, luminosity and flux. Description: An acrylic setup with two light bulbs on dimmers. One bulb has a globe covering. |
 |
6B 40.30 - Black Body Radiation:
Demonstrates: Infrared radiation from heat. Description: A metal ring is heated and observed with a CCD camera. The ring will appear on the screen before it can be seen by the naked eye. |
