Consider a room heater that uses a concave mirror to reflect
infrared radiation from hot coils. The mirror has a radius of
curvature of 51.0 cm and produces an image of the
coils 3.10 m away from the mirror. Calculate the
intensity of IR radiation in W/m2 projected by
the concave mirror on a person 3.10 m away. Assume
that the heating element radiates 1,450 W and has an
area of 110 cm2, and that half of the
radiated power is reflected and focused by the mirror.
