ANALYSIS
Examine the graph of light intensity vs distance.
*** Does it appear to be consistent with the model you predicted in the Preliminary Questions?
*** How can you tell?
*** How well does the model fit your experimental data? Do your data approximately follow
an inverse square function? Does the equation agree with your model of light intensity using
the concentric spheres?
