What is the relationship between intensity and distance from a point source? Why should this be the cast? (Hint: think of the point source as being at the center of the sphere. How are the area of this sphere and the intensity of light related? It might help you to realize that no matter how far away you are the toal power output from the point source is the same. In other words, if you enclose a 50W light bulb...

A 100-W incandescent lightbulb radiates visible light at a rate of about 10.0 W; the rest of the EM radiation is mostly infrared. Assume that the lightbulb radiates uniformly in all directions. Under ideal conditions, the eye can see the lightbulb if at least 20.0 visible photons per second enter a dark-adapted eye with a pupil diameter of 7 mm. Estimate how far from the source the lightbulb can be seen under these rather extreme conditions. Assume an average wavelength...
