I'm working on a project and don't have access to a physics book so I'm asking for help. I need to find the intensity of light at a certain distance over a given rectangular area from a cylindrical light source.
The source is 18in long, 1in in diameter, and outputs 2.6watts. I need the light intensity at 6in away over 18in^2.
All I could find in a quick search online is intensity from a point source instead of my cylindrical source. I'm not sure how this changes everything.
Thanks for any help,
Jake
