You direct a 20.0 mW laser beam toward a reflecting surface at normal incidence. The cross section of the beam has a diameter of 2.65 mm when it arrives at the surface. If 87% of the beam is reflected from the surface, what is the total pressure on it due to the incident and reflected energies? N/m2 Submit Answer [-/1 Points] DETAILS SERPSEWA10 33.WA.032.
