1. Describe how the spectra from each light source differs from the others. What accounts for these differences?
2. How would the spectra of other light source (for example: TV's, metal halide bulbs, fire) compare to those from #2 above? How would you use these spectra to determine what comprises these light sources?
Pin Hole Viewer Experiment
1. What is the diameter of the sun using your pinhole viewer? How does your determined diameter compare to the accepted diameter of the sun?
2. Use the viewer to determine the moon's diameter (use it on a night with a full or near-full moon). How does your determined diameter compare to the accepted diameter of the moon?
3. How much larger is the sun than the moon? Why do both appear the same size in the sky?
