1. The spectrum emitted by a light source is independent of the intensity of the light. Although brighter or dimmer, the wavelengths produced will remain the same.
Instructor Procedure
Step(s) to Follow | Expected Result |
---|---|
1. Turn on Power Stat. 2. Ask students to look through the diffraction grating at the light. | They will see a continuous emission spectrum. |
1. Adjust the dial on the power stat. | The light bulb will grow brighter or dimmer. They will see a continuous emission spectrum, but it will grow either brighter or dimmer as the light source does. |
