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...

There are three types of conditions by which the eye can not focus properly; myopia, hyperopia and astigmatism. Here we will explore only myopia and hyperopia. In myopia (for various reasons) the image within the eye focuses on a point in the vitreous humor and not in the retina. This causes the eye to be unable to correctly focus on distant objects. In hyperopia (for various reasons) the image focuses on a point farther away than the retina outside the...
