Question 5.5. A ray of red light traveling through air strikes a block of quartz at an angle of incidence of 40°. If that light travels through the quartz and then enters a large crystal of sodium chloride (salt), what is the angle of refraction of the light in the sodium chloride? Quartz has an index of refraction of 1.46, while sodium chloride's index of refraction is 1.54.
