33.48 • After a long day of driving you take a late-night swim in a motel swimming pool. When you go to your room, you realize that you have lost your room key in the pool. You borrow a power- ful flashlight and walk around the pool, shining the light into it. The light shines on the key, which is lying on the bottom of the pool, when the flashlight is held 1.2 m above the water surface and is directed at the surface a horizontal distance of 1.5 m from the edge (Fig. P33.48). If the water here is 4.0 m deep, how far is the key from the edge of the pool? Figure P33.48 1.2 m 1.5 m 4.0 m

Figure 25.49 shows a light bulb between two mirrors. One minor produces a beam at light with parallel lays; the other keeps light from escaping without being put into the beam. Where is the filament of the light in relation to the focal point or radius of curvature of each mirror? Figure 25.49 The two mirrors trap most of the bulb’s light and form a directional beam as in a headlight.
Explain why the “invisible man” would be unable to see.
Brewster plates are used in laser cavities to polarize the light with the smallest amount of power loss possible (see figure). Suppose the laser cavity is filled with air (n = 1) and the Brewster's plate is made of glass (ng = 1.47). (a) What is the angle the normal to the plate must make with respect to the laser beam, θB, if the polarization of the reflected light is maximized? Answer in radians. (b) If instead this were a dye laser, whose cavity is filled with a liquid solution with ns = 1.3. What is the angle, θB, in radians?
If the are area, A, of the beam of light is tripled, by what factor does the intensity change? Question 11 options: a) 9 b) 3 c) √ 3 d) it does not change e) none of these are correct
If you have completely polarized light of intensity 170 W/m2, what will its intensity be after passing through a polarizing filter with its axis at an 88.5° angle to the light's polarization direction? =____mW/m2
Unreasonable Results To save money on making military aircraft invisible to radar, an inventor decides to coat them with a non-reflective material having an index of refraction of 1.20, which is between that of air and the surface of the plane. This, he reasons, should be much cheaper than designing Stealth bombers. (a) What thickness should the coating be to inhibit the reflection of 4.00-cm wavelength radar? (b) What is unreasonable about this result? (c) Which assumptions are unreasonable or inconsistent?
Referring to the electric room heater considered in the first example in this section, calculate the intensity of IR radiation in W/m2 projected by the concave mirror on a person 3.00 m away. Assume that the healing element radiates 1500 W and has an area of 100 cm2, and that half of the radiated power is reflected and focused by the mirror.
(a) Light reflected at 62.5° from a gemstone in a ring is completely polarized. Can the gem be a diamond? (b) At what angle would the light be completely polarized if the gem was in water?
Verify that the correct value for the speed of light c is obtained when numerical values for the permeability and permittivity of free space (0 and 0) are entered into the equation c=100.
Three polarizers are arranged as shown in Figure 25-46. If theincident beam of light is unpolarized and has an intensity of1.60 W>m2, find the transmitted intensity (a) when u2 = 25.0°and u3 = 50.0°, and (b) when u2 = 50.0° and u3 = 25.0°
7. The answer at which light can by completely removed by an analyzer and a polarizer would be:a. 0 ob. 45 oc. 90 od. 180 oe. 360 o
An unpolarized light with an initial intensity of ?0 is incident on two polarizers.What must be the angle between the transmission axes of the two polarizers for the intensity of light to be 3/8 of ?0 after passing through the second polarizer?
