(EMW-4) A laser has an intensity of 105 W/m2 (this is the average value of the Poynting vector) The beam is circular, with a diameter of 2.00 mm. The laser is directed at a black surface that absorbs all the energy that hits it. (a) Find the amplitudes of the electric and magnetic fields (Eo and Bo) in the laser beam. (b) Find the maximum energy density of each of these fields (ue and us). (c) How much energy does the surface absorb in 3.00 minutes? 1 2.00 mm
