Light Intensity

Light intensity varies by the strength of the light bulb as well as the distance to the light bulb. Pupils apply these concepts independently at first. They must solve for the light intensity as either the distance or the wattage of the light adjusts. To finish, they must figure it for problems where both the wattage and the distance changes.
