1. The problem statement, all variables and given/known data A 60 W monochromatic point source is radiating equally in all diresctions in a vacum. What is the electric field amplitude 2m from the source. 2. Relevant equations Intensity=Power/(4*Pi*r^2), Intensity proportional to square Amplitude 3. The attempt at a solution I=1.19 Wm-2 what happens next?
