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.1° (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.
1°
Explanation / Answer
ndsin(1)=ngsin(2)
nd - index of refraction of diamond ng - index of refraction of glass 1 - angle of incidence 2 - angle ofrefraction
for blue:
2b = 49.62o
for red:
2r = 49.16o
Angle between the two refracted rays
= 2b - 2r = 49.62- 49.16 = 0.46 o
