Refractive Index Problem invloving prism (Please Help)
What is given is a prism, angle of deviation and apex angle, I also have to find refractive index of the prism.
To solve the problem I must prove that:
Nprism = sin((A+d)/2)/ sin(A/2)
The diagram given of the Prism:

n sin(i) = nprism sin (r)
3. My attempt at a solution
nprism = sin(i1)/sin(r1)
therefore i1 = (A+d)/2 and r1 = (A/2)
just need to figure i1 = (A+d)/2 and r1 = (A/2) by proving
Please Note: My solution so far may be completely wrong, any help given would be very much appreciated :)
