Question: A narrow beam of light with wavelengths from 450 nm to 700 nm is incident perpendicular to one face of a 38.00{\rm ^\circ} prism made of crown glass, for which the index of refraction ranges from n \;= \;1.533 to n\; =\; 1.517 for those wavelengths. What is the angular spread of the beam after passing through the prism?
