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
