## Question

###### Isotropic electromagnetic waves expand uniformly outward in all directions in three dimensions. Electromagnetic waves from a small, isotropic source are not plane waves, which have constant maximum amplitudes.a) How does the maximum amplitude of the electric field of radiation from a small, isotropic source vary with distance from the source?b) Compare this with the electrostatic field of a point charge.
