A room heater uses a concave mirror to reflect infrared radiation from hot coils. The mirror has a radius of curvature of 55.0 cm and produces an image of the coils 3.40 m away from the mirror. What is the intensity of IR radiation in W/m2 projected by the concave mirror on a person 3.40 m away? The heating element radiates 1,750 W and has an area of 130 cm2, and half of the radiated power is reflected and focused by the mirror
