Consider a room heater that uses a concave mirror to reflect infrared radiation from hot coils. The mirror has a radius of curvature of 49.0 cm and produces an image of the coils 3.10 m away from the mirror. Calculate the intensity of IR radiation in W/m^2 projected by the concave mirror on a person 3.10 m away. Assume that the heating element radiates 1,350 W and has an area of 130 cm^2, and that half of the radiated power is reflected and focused by the mirror.
