What do you mean by angle of deviation of a ray in case of refraction through a prism. Calculate the expression of the angle of deviation.

Discuss the phenomenon of refraction through a prism and prove that for a prism: mu=(sin(A + delta_m)//2)/(sin A//2) ,where A is anle of prism, mu s refractive index of the material of prism and delta_m is the ngle of minimum deviation.

Draw a diagram to show refraction through a prism and mark angle i, angle r_1 , angle r_2 angle d, and angle of emergence.
