what happens when angle of incidence is increased to large amount in thin prism...is angle of prism in this case differences of angle of retraction..i.e.A=r1-r2. ?

As we keep on increasing the angle of incidence, The angle of deviation decreases at first, reaches a minimum and then starts increasing. However, the angle of prism always remains the sum of r1 and r2.
