A certain kind of glass has nblue-1.64 for blue light and nred = 1.58 for red light. If a 5. am of white light (containing all colors) is incident at an angle of 35°, what is the angle between the red and blue light inside the glass? be

Answer 1

Then using Snell's Law we have for blue 1*sin(35^o) = 1.64*sin(?_b)..
so ?_b = sin^-1(sin(35)/1.64) = 20.47^o

For red ?_r =sin^-1(sin(35)/1.58) = 21.28^o

So the difference in the angle 21.28° - 20.47° = 0.81^o

answer is: 0.81^o
