QUESTION:

Problem 56PE

Find the magnification of the heater element in Example 25.9. Note that its large magnitude helps spread out the reflected energy.

Example 25.9: A Concave Reflector

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, where are the coils?
