For free space show that electromagnetic $($EM$)$ wave is transverse in nature.

Show that for free space, the total outward flux of EM energy through surface S bounding volume V is equal to the rate of loss of EM energy from the volume V$.$A laser beam of $2$ mm diameter has average power of $20$GW$.$ Calculate the peak values of electric and magnetic fields in the laser beam.
