Answer #1

For a continuous sinusoidal electromagnetic wave, the average intensity Iavg is given by, , where, c is the speed of light, μo is the permeability of free space, and Eo is the maximum electric field strength.

Given, Iavg = 3.05 W/m2

Known, c = 3 x 108

μo = 4 x 10-7

Thus, the maximum value of the electric field in the given electromagnetic wave is 47.955 V/m
