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?

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 52 cm and produces an image of the coils 2.6 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...

(33%) Problem 3: Warm blooded animals are home otherm that is, they maintain an approximately constant body temperature. (For humans it's about 37°C.) When they are in an environment that is below their optimum temperature, they use energy derived from chemical reactions within their bodies to warm them up One of the ways that animals lose energy to their environment is through radiation. Every object emits electromagnetic radiation that depends on its temperature. For very hot objects like the sun,...
