Chapter 24 Wave Optics Quick Quizzes 1. (c). The fringes on the screen are equally spaced only at small angles where tan sin θ θ is a valid approximation. 2. (b). The space between successive bright fringes is proportional to the wavelength of the light. Since the wavelength in water is less than that in air, the bright fringes are closer together in the second experiment. 3. (b). The outer edges of the central maximum occur where

Unformatted text preview: sin a λ = ± . Thus, as a , the width of the slit, becomes smaller, the width of the central maximum will increase. 4. The compact disc. The tracks of information on a compact disc are much closer together than on a phonograph record. As a result, the diffraction maxima from the compact disc will be farther apart than those from the record. 303...
