A plane electromagnetic wave has an energy flux of 711 wm2, Ask an Expert

Academics

A plane electromagnetic wave has an energy flux of 711 W/m². A flat, rectangular surface of dimensions 100 cm × 24 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 × 10⁸ m/s.

a) Calculate the total energy absorbed by the surface in 1.1 min. Answer in units of J.

b) Calculate the momentum absorbed in this time. Answer in units of kg · m/s
