Consider a room heater that uses a concave mirror to reflect infrared radiation from hot coils. The mirror has a radius of curvature of 54.5 cm and produces an image of the coils 3.25 m away from the mirror. Find the magnification of the heater element. Note that its large magnitude helps spread out the reflected energy.
