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.
|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.|
