3) A red laser with a 651nm wavelength, produces a 0.02 W beam with a 3mm diameter traveling left (-x direction). At a certain time (t=0) there is a magnetic field maximum pointing up at the origin. a) [4] For this E-M wave, determine the maximum magnetic field. b) [4] Determine the electric field amplitude and direction at the origin at =0. c) [4] On the axis below sketch the electric and magnetic fields at t=0 for this E-M wave as a function of position.
