Solved: The intensity I of light from an isotropic point
Chapter 33, Problem 18(choose chapter or problem)
The intensity I of light from an isotropic point source is determined as a function of distance r from the source. Figure 33-37 gives intensity I versus the inverse square ...., r- 2 of that distance. The vertical axis scale is set by Is = 200 W 1m2, and o the horizontal axis scale is set by r;2 = 8.0 m-2 What is the power of Fig.33-37 18. the source?
