Information is stored on an audio compact disc, CD-ROM, or DVD disc in a series of pits on the disc. These pits are scanned by a laser beam. An important limitation on the amount of information that can be stored on such a disc is the width of the laser beam. Explain why this should be, and explain how using a shorter wavelength laser allows more information to be stored on a disc of the same size.
34.17 A speck of dirt is embedded 3.50 cm below the surface of a sheet of ice (n=1.309). What is its apparent depth when viewed at normal incidence?
Two small stereo speakers A and B that are 1.40 m apart are sending out sound of wavelength 34 cm in all directions and all in phase. A person at point P starts out equidistant from both speakers and walks so that he is always 1.50 m from speaker B (Fig. E35.1). For what values of x will the sound this person hears be (a) maximally reinforced, (b) cancelled? Limit your solution to the cases where x 1.50 m.
Could x-ray diffraction effects with crystals be observed by using visible light instead of x-rays? Why or why not?
Monochromatic coherent light passing through two thin slits is viewed on a distant screen. Are the bright fringes equally spaced on the screen? If so, why? If not, which ones are closest to being equally spaced?
