Carefully write down the fit equation and consider the following questions.
1. Is a linear function a good fit to the data?
2. Compare the fit equation to the equation for a straight line: y = mx + c.

Setup and Procedure:
1. Switch on the laser source about 15 minutes before the experiment is due to start.
This ensures that the intensity of light from the laser source is constant.
2. Allow the
