Electric room heaters use a concave mirror toreflect infrared (IR) radiation from hot coils.Note that IR radiation follows the same law ofreflection as visible light. The mirror has aradius of curvature of 40 cm and produces animage of the coils 340 cm away from themirror.How far away are the coils from the mirror? cmaway.What is the absolute value of the magnificationof the heater element? Magnification = .Note that its large magnitude helps spread outthe reflected energy. Can you see why that isuseful for this device?

Problem 6: 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 49 cm and produces an image of the coils 3.2 m away from the mirror.
Building contractors often install double-glazed windows to prevent thermal energy (heat) from entering or exiting a building. In addition to being effective insulators, such windows present interesting optical effects. glass In the figure, a double-glazed window consists of two identical panes of glass (ng = 1.46), each yg = 12.0 mm air thick, separated by an air gap of y, = 9.60 mm. If light incident on the glass makes an angle of o = 40.00° with respect to the glass, find the shift in path Ax as the light glass enters the room. Use na = 1.00 for the index of refraction of air. Ax = mm
A light ray traveling in air is incident on one face of a right-angle prism with index of refraction n = 1.49, as shown in Figure P22.54, and the ray follows the path shown in the figure. Assuming that θ = 58.0° and the base of the prism is mirrored, determine the angle made by the outgoing ray with the normal to the right face of the prism.?degrees
An experimenter at an optical research company finds it difficult to experiment, as the measuring device that determines the angle φ inside the mirror always interferes with light progression. In this case, it would be good to measure the angle δ outside the mirror. So how does β, the relative angle of reflection with respect to the angle of incidence, relate to the angle δ?
Optical fibers are a central part of technology for rapid information transmission with a high level of efficiency. A new type of optical fiber is crafted with an index of refraction n = less than that of water in the vicinity of room temperature, where NH2O fact that n < nH20 potentially problematic if the fiber should be submerged? 1.25 = 1.33. Why is the O A. Total internal reflection would be frustrated, allowing loss of signal. O B. Internal reflection would actually be enhanced, so there is no problem. C. Electric eels might have free internet access.
X rays are typically used to kill off cancer cells, however an issue some radiologists run into is the damage an x-ray may do to surrounding tissue. Because of this, accuracy plays a key role in radiation therapy. Suppose you are a medical physicist, and you have been given the task of choosing a medium with a proper index of refraction to bend the x rays such that they only hit the tumor. Suppose you know that the x ray comes in at an angle of 20 degrees with respect to the normal of your second medium. You know the tumor expands out to 5 degrees on either side of the normal what is the minimum index of refraction needed for the x ray to hit the tumor
Please refer to Figure 2 included. A light beam shines through air and then strikes a mirror, making an angle theta = 66.3 degrees with respect to the vertical, as shown. The reflected beam then strikes a pane of glass of thickness h = 1.01 cm, located a distance y= 32.2 cm from the mirror, and then exits the glass pane at the bottom, a horizontal distance x cm away from where it struck the mirror. What is the value of x? 74.1 cm 29.6 cm 103.7 cm 44.5 cm
