Use the worked example above to help you solve this problem. A
light ray of wavelength 589 nm (produced by a sodium lamp)
traveling through air is incident on smooth, flat slab of crown
glass at an angle 𝜃1 of 39° to the
normal, as sketched in the figure.
(a) Find the angle of refraction, 𝜃2.
°
(b) At what angle 𝜃3 does the ray leave the
glass as it re-enters the air?
°
(c) How does the answer for the 𝜃3 change if
the ray enters water below the slab instead of the air?
°
EXERCISE HINTS: GETTING
STARTED | I'M STUCK!
Suppose a light ray in air (n = 1.00) enters a
cube of material (n = 2.50) at
a 46.0° angle with respect to the normal and then exits
the bottom of the cube into water (n = 1.33). At what
angle to the normal does the ray leave the slab?
