"Questions for tonight: 1) What type of light source would NOT give you and INVERSE curve for light intensity on a graph? Why?
After reading through a few of the other blogs and doing some of my own research, I would have to agree with those who said that the light source that would not give you an inverse curve would be light using a parabola reflector. Parabola reflector can best be described as a round mirror. If you can imagine a parabola than you can easily picture a parabolic reflector. You can also use the equation x^2=y to graph the parabola. The parabolic reflector works by all the rays entering parallel to the axis and reflect to the focus. To help explain this to my students I would use drawings and actually show them what was happening.
