Q1) The amplitude of an electromagnetic wave is E0 = 471.0 V/m. Find the following values.
(a) Erms
333.047 V/m
(b) Brms
__ nT
(c) the intensity I
__W/m2
(d) the radiation pressure Pr
__nPa
Q2)(a) For a given distance from a radiating electric dipole, at what angle (expressed as θ and measured from the dipole axis) is the intensity equal to 83 percent of the maximum intensity?
(b) At what angle θ is the intensity equal to 3 percent of the maximum intensity?
I'm not sure what the general formulas are.
