parkernewton Posted November 11, 2012 Report Share Posted November 11, 2012 The index of refraction for blue light of wavelength 4.5 X 10^(-7) m for a particular kind of glass is 1.328 and for red light of wavelength 6.5 X 10^(-7) m it is 1.321. An equilateral triangular prism is made out of this glass and white light is incident on it parallel to one of its bases. Find the angles the blue and red rays make with the normal as they emerge from the prism. What is the deviation of each ray?Solution:The fact that the solution is an angle would hint that Snell's Law must be used. However, Snell's law only applies to refraction from a rarer to a denser medium, and in this case the light rays, emerging from the prism, are traveling from a denser to a rarer medium?
