25.5 Dispersion: The Rainbow and Prisms
Index of refraction varying with wavelength, so white light fans into colors in prisms and raindrops but blurs images in lenses.

25.5 Exercise 2
A beam of white light goes from air into water at an incident angle of . At what angles are the red (660 nm) and violet (410 nm) parts of the light refracted?
25.5 Exercise 4
(a) A narrow beam of light containing yellow (580 nm) and green (550 nm) wavelengths goes from polystyrene to air, striking the surface at a incident angle. What is the angle between the colors when they emerge? (b) How far would they have to travel to be separated by 1.00 mm?
25.5 Exercise 6
A ray of 610 nm light goes from air into fused quartz at an incident angle of . At what incident angle must 470 nm light enter flint glass to have the same angle of refraction?
