*16 Babinet's principle. A monochromatic beam of paral- lel light is incident on a "colli- mating" hole of diameter x> A. Point P lies in the geometrical shadow region on a distant screen (Fig. 36-39a). Two dif- fracting objects, shown in Fig. 36-39b, are placed in turn over the collimating hole. Object A is an opaque circle with a hole in it, and B is the "photographic negative" of A. Using superpo- sition concepts, show that the intensity at P is identical for the two diffracting objects A and B. Screen (a) (6)

POSSIBLE POINTS In the summer, people often wear light colored clothing to stay cool. This is a good idea because light colors tend to electromagnetic waves. reflect refract absorb 1 4 7 8. 9.
X-rays of wavelength 0.130 nm are reflected from a certain crystal, and the first-order maximum occurs at an angle of 14.2°. What value does this give for the interplanar spacing of the crystal? ____nm
A ray of blue light, randomly polarized, travelling in air (n=1.0) is incident on the surface of a transparent material (n = 1.6) at an angle of 45°. Calculate the ratio of intensities for reflected s- and p-polarized light, Is/Ip. (10)
..54 Dispersion in a window pane. In gle e Fig. 33-54, a beam of white light is incident at an- 50° on a common window pane (shown in cross section). For the pane's type of glass, the index of refraction for visible light ranges from 1.524 at the blue end of the spectrum to 1.509 at the red end. The two sides of the pane are paral- lel. What is the angular spread of the colors in the beam (a) when the light enters the pane and (b) when it emerges from the opposite side? (Hint: When you look at an object through a window pane, are the colors the light from the object dispersed as shown in, say, Fig. 33-20?) = Ꮎ Figure 33-54 Problem 54.
10. A light ray of given wavelength, initially in air, strikes a 90° prism at P (see Fig. 39-53) and is refracted there and at Q to such an extent that it just grazes the right-hand prism surface at Q. (a) Determine the index of retraction of the prism for this wavelength in terms of the angle of incidence , that gives rise to this situation. (b) Give a numerical upper bound for the index of refraction of the prism.
