The magnetic field in an electromagnetic wave has a peak value given by b = 4.8 μt . part a part complete for this wave, find the peak electric field strength. express your answer using two significant figures. e = 1.4 kv/m submitprevious answers correct part b find the peak intensity. express your answer using two significant figures.

The relationship between intensity of the magnetic field B and intensity of the electric field E for an electromagnetic wave is given by

where  is the speed of light.

This relationship holds also for the peak intensity of the two fields. Since the peak intensity of the magnetic field is

we can use the previous relationship to find the peak value of the electric field:
