A flint-glass prism is made in the shape of a 30 degree-60 degree-90 degree triangle. Red and violet light are incident on the prism at right angle to it's vertical side. The index of refraction n red= 1.66, n violet = 1.70. What angle does each ray make with the horizontal when it emerges from the prism?
The law of refraction says:
n1 sin(angle1) = n2 sin(angle2)
where n1 is the index of ...
with formulas and explanations, the problem is solved
