A plane electromagnetic wave has an energy flux of 1108 W/m . A flat, rectangular sur- face of dimensions 77 cm x 21 cm is placed perpendicular to the direction of the wave. The surface absorbs half of the energy and reflects half. The speed of light is 2.99792 x 10 m/s. Calculate the momentum absorbed in 1.1 min. 1. 8.61478 x 10-5 2. 2.84897 x 10-6 3. 2.51622 x 10-5 4. 1.85105 x 10-5 5. 1. 15554 x 10-5 6. 5.91649 x 10-5 7. 0.000204494 8. 6.68726 x 10 5 9. 1.48429 x 10-5 10. 0.000174757 Answer in units of kg . m/s
