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.
Find the magnification of the heater element, given that the mirror has a radius of curvature of 46cm and produces an image of the coils 3.4 m away from the mirror?

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. __________

Consider a room heater that uses a concave mirror to reflect infrared radiation from hot coils. The mirror has a radius of curvature of 55.0 cm and produces an image of the coils 2.70 m away from the mirror. Calculate the intensity of IR radiation in W/m2 projected by the concave mirror on a person 2.70 m away. Assume that the heating element radiates 1,350 W and has an area...

Deep in the physics and astronomy basement storeroom, you find a very large concave spherical mirror from an old telescope. The mirror is 2 m across, and has a radius of curvature of 14.0 m. Because this is just a small piece of such a large sphere, the angle of incidence for on-axis rays will always be below 5°, minimizing spherical aberration You try out the mirror for use as a full-length wall mirror.
