Dear student...
It is a very good question about the prisms. Let us start our discussion regarding the situation from the level that you have a minimal idea about the refraction in prisms.
I think you have an idea about the expression for the refractive index of a prism given by:

u = (sin((A+D)/2)/(sin(A/2)), where A represents the angle of the prism and D stands for the angle of minimum deviation. For any incident ray the refraction in a prism will be as given in the following figure.
