Chapter 25, Problem 35PE
A narrow beam of white light enters a prism made of crown glass at a 45.0° incident angle, as shown in Figure 25.57. At what angles, θR and θV, do the red (660 nm) and violet (410 nm) components of the light emerge from the prism?
Figure 25.57 This prism will disperse the while light into a rainbow of colors. The incident angle is 45.0°, and the angles at which the red and violet light emerge are θR and θV.

A ray of sunlight traveling through water (n=1.32 - 1.34 across the visible spectrum) has an
incident angle of 80° when it encounters a transparent aquarium wall with index of refraction
n=1.2. There is air with index n=1 on the other side of the wall and the wall surfaces are
parallel. Which statement below is true?
Select one:
a. Light emerges on the other side of the wall traveling parallel to the incident ray.
b. Light emerges on the other side of the wall but different colors now travel in different directions.
c. Light emerges on the other side of the wall and is now completely polarized.
d. The light is completely reflected at the first interface.
e. The light enters into the transparent wall bot is completely reflected at the second interface.

A beam of white light is incident on the surface of a diamond at an angle a.(
Figure 1) Since the index of refraction depends on the light's wavelength, the
different colors that comprise white light will spread out as they pass through the
diamond. The indices of refraction in diamond are nred= 2.410 for red light and
nblue = 2.450 for blue light. The surrounding air has nair = 1.000. Note that the
angles in the figure are not to scale.
