Q1) The amplitude of an electromagnetic wave is E0 = 471.0 V/m. Find the following values.(adsbygoogle = window.adsbygoogle || []).push({});

(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.
