Homework Statement
The index of refraction for violet light in silica flint glass is 1.65 and for red light is 1.62.What is the angle of deviation for the red ray passing through a prism of apex angle 59.7 degrees. If the angle of incidence is 47.4 degrees.
Homework Equations
nglass sine theta3 = nredlight sine theta4
nredlight sine theta1 = nglass sine theta2
Angle of deviation = [theta 1 + theta 4 ] - apex angle
The Attempt at a Solution
I know the equations to be used. but I don't understand the figure that accompanies this problem in the textbook. Can someone post a general picture, with all of these angles labeled and provide a starting thrust?
Thank you!
