Choose the one alternative that best completes the statement or answers the question. 1) The doublet of the sodium spectrum, in the yellow band, has two constituents having lengths of 589.0 nm and 589.6 nm, respectively. Light of this doublet is propagated at normal incidence through a crystal slab. The index of refraction of the crystal at these wavelengths is 1.548. The number of waves of the 589.0- nm constituent that are present in a crystal 1.3 mm thick is closest to: A) 2200 B) 5300 C) 3400 D) 4300 E) 2700 1) 2) The doublet of the sodium spectrum, in the yellow band, has two constituents having lengths of 589.0 nm and 589.6 nm, respectively. Light of this doublet is propagated at normal incidence through a crystal slab. The index of refraction of the crystal at these wavelengths is 1.286. The number of waves that are present in a crystal is different for each constituent. The difference in the number of waves, in a particular crystal, is one whole wave.

The angle of refraction is one- half the angle of reFection. The angle of refraction is closest to: A) 34 B) 38 C) 30 D) 36 E) 32 3) 4) A ray in glass is incident onto a water- glass interface, at an angle of incidence equal to half the critical angle for that interface. The indices of refraction for water and the glass are 1.33 and 1.60, respectively. The angle that the refracted ray in the water makes with the normal is closest to: A) 30 B) 35 C) 25 D) 40 E) 45 4) 5) The critical angle for an air- glass interface is 61.9. A ray in air is incident on the interface. The reFected ray is 100% polarized. The angle of refraction is closest to: A) 39.6 B) 40.8 C) 39.0 D) 41.4 E) 40.2 5) 6) A glass plate whose index of refraction is 1.51 is immersed in a liquid. The surface of the glass is inclined at an angle of 50 with the vertical. A horizontal ray in the glass is incident on the interface. When the liquid is a certain alcohol, the incident ray arrives at the interface at the critical angle. The index of refraction of the alcohol is closest to: A) 1.12 B) 1.18 C) 1.14 D) 1.16 E) 1.10 6) 7) A glass plate whose index of refraction is 1.62 is immersed in a liquid. The surface of the glass is inclined at an angle of 37 with the vertical. A horizontal ray in the glass is incident on the interface. The liquid is an oil whose index of refraction is 1.40. The incident horizontal ray refracts at the interface. The angle that the refracted ray, in the oil, makes with the horizontal is closest to: A) 3.6 B) 8.9 C) 11 D) 7.1 E) 5.4 7) 1 Figure 33.1a 8) A ray in glass arrives at the glass- water interface at an angle of 48 with the normal. The refracted ray, in water, makes a 65 angle with the normal. The index of refraction of...
