So, why are we making you measure these areas? The flashlight only has so much power, and the black tube restricts the light coming from the flashlight into a cylinder. Thus, there is only a certain amount of light allowed to come out and hit the ground. Let's say there are "one hundred units of light" emitted by the flashlight. Now let's convert this to how many units of light hit each square centimeter at angles of 90° and 45°. D7. At 90°, the amount of light per centimeter is 100 divided by the Area of the circle = ________________________ units of light per cm2. (1 pt) D8. At 45°, the amount of light per centimeter is 100 divided by the Area of the ellipse = _______________________ units of light per cm2. (1 pt)
