A plane electromagnetic wave has an intensity of 750W/m2. A flat, rectangular surface of dimensions 50 cm x 100 cm is placed perpendicular to the direction of the wave. The surface absorbs half of the energy and reflects half. Calculate (a) the total energy absorbed by the surface in 1.00 min and (b) the momentum absorbed in this time.
