Homework Statement
An isotropic point source radiates electromagnetic energy, and its output is measured by a thin disc-like detector of radius R. Calculate the power measured by the detector at distance h from the source, assuming that the plane of the disc is orthogonal to the line of sight between source and disc centre.
Homework Equations
beer's law, and inverse square law
The Attempt at a Solution
i tried calculating the intensity over a radius, and integrating it over the whole circle.
