The rms electric field of an electromagnetic wave increases from 307 to 921 N/C.
(a) Determine the wave intensities for the two values of the electric field.
(b) What is the rms magnetic field associated with each electric field?
(c) Determine the wave intensity for each value of the magnetic field.
