The electric and magnetic fields of a plane electromagnetic wave are given by the formulas below, where and are both in meters and is in seconds. This wave is traveling through a medium whose index of refraction is 1.3.
Reminder: The "x.xxenn t" notation in the sine functions means " t".
= 2.8 z + 1.19e16 V/m
= z + 1.19e16 Tesla
(a) In what direction does the wave propagate?
(b) What is the magnitude of
What is the direction of (assuming that the symbol is positive)?
(c) What is the wavelength of the wave (in meters)?
