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. The coils are 24.424.4 cm away from the mirror, and an image of the coils is 3.503.50 m away from the mirror. Find the magnification of the heater element.
