Electric room heaters use a concave mirror to reflect infrared (IR) radiation from hot coils. Note that IR follows the same law of reflection as visible light. Given that the mirror has a radius of curvature of 50.0 cm and produces an image of the coils 3.00 m away from the mirror, the coils are therefore 27.3 cm away from the mirror. Find the magnification of the heater element. Note that its large magnitude helps spread out the reflected heat.
