Learning Goal:

To practice Problem$-$Solving Strategy $32\mathrm{.}1$ Electromagnetic Waves.

An electromagnetic wave in a vacuum traveling in the $+$x direction generated by a variable source initially has a wavelength of $305$ mm and a maximum electric field EmaxEmax in the $+$y direction of $7\mathrm{.}10103$ V$/$mV$/$m $.$ If the period of the wave is then increased by a factor of $1\mathrm{.}80,$ what is the equation of the resulting magnetic field component of the wave? Which quantities appear in the equation for the magnetic field component of an electromagnetic wave?
