Chapter 24
1. (p.752 prob.4) Monochromatic light falls on two very narrow slits 0.040mm apart. Successive fringes on a screen 5.00m away are 5.5cm apart near center of the patern. What is the wavelength and frequency of the light?
2. (p.753 prob.16) A parallel beam of light containing two wavelengths, l = 400nm and l = 65nm, enters the silicate flint glass of an equilateral prism as shown in Fig. 24-49. At what angle does each beam leave the prism (give angle with normal to the face)?
3. (p.753 prob.22) How wide is the central diffraction peak on a screen 2.50m behind a 0.0348-mm-wide slit illuminated by 589-nm light?
4. (p.75 prob.29) Light falling normally on a 10,000-line/cm grating is revealed to contain three lines in the first-order spectrum at angle of 31.2°, 36.4°, and 47.5°. what wavelengths are these?
5. (p.754 prob.43) A fine metal foil separates one end of two pieces of optically flat glass, as in Fig. 24-32. When light of wavelength 670nm is incident normally, 28 dark lines are observed (with one at each end). How thick is the foil?
6.(p. 755 prob.58) Two Polaroids are aligned so that the light passing through them is a maximum. At what angle should one of them be placed so that the intensity is subsequently reduced by half?
