[c] A dentist's lamp has a visible light luminosity of 1.1
joules per second. If the lamp is moved to a distance of X meters
away from a patient's teeth, what is the flux of the lamp on the
teeth? Then, making a reasonable estimate of the surface areas
involved, how much energy shine from the lamp onto a single tooth
over a time period of Y seconds?
Y=120, X=0.5995
