Problem
From everyday experience and observations, estimate the brightness of a full moon as compared to the noon day sun. Brightness is defined as the luminous intensity as measured in units of power per unit area. To arrive at a reasonable numerical estimate, you will need to estimate some physical parameters. It is essential that you explain the reasoning behind your estimates and include detailed drawings and explanations to support your arguments.
