Question

A ray of sunlight is passing from diamond into crown glass; theangle of incidence is 28.50°. Theindices of refraction for the blue and red components of the rayare: blue (ndiamond =2.444,ncrown glass =1.531), and red (ndiamond =2.410,ncrown glass =1.520). Determine the angle between the refracted blue andred rays in the crown glass.

Explanation / Answer

use snells law to find the angle of refraction for each, thensubtract to get the angle between them . red light:       2.410sin28.50 = 1.520sin           = 49.161 degrees . blue light:      2.444 sin28.50 = 1.531sin           = 49.615 degrees . angle between them = 49.615 - 49.161   = 0.454 degrees
