Additional prisms and of identical shape and material are now added to as shown in the figure. The ray will suffer
a) |
Same deviation |
b) |
Greater deviation |
c) |
Total internal reflection |
d) |
No deviation |

(a) Since prism is placed in position of minimum deviation, therefore refracted rays becomes parallel to the base of the prism, again by adding two prism and of same material as shown in figure, the deviation produced by and equal and opposite in sense, therefore final deviation is same as due to prism . |
