4. What is the inverse square law?
5. If you must move to reduce the amount of flash reaching your subject, how far do you move?

2. b Relative aperture. The opening on a long lens must be larger than a corresponding opening on a short lens to produce the same f-stops.
3. c The intensity of the illumination is inversely proportional to the square of the distance from light to subject. At twice the distance from the subject, the light illuminates only 1/4 of the original.
4. d Two (f/8 > f/11 > f/16)
5. e To create a 1-stop difference, multiply the original distance by 1.4. Example - if you were originally 5 feet away, a 1-stop difference would have you step back to 7 feet.
