Question

To find the refractive index of a prism observations

Answer 1

Answer:

Refractive index of prism is given by

n = sin (A+ D)/2 / sin A/2

Answer 2

Explanation:

Answer:

The angle between these two rays is angle of deviation denoted by 'D'. Do the same for various angles of incidence such as 40°, 50° etc. If we take angle of incidence along x-axis and the angle of deviation along y-axis we get the graph as shown in figure. The refractive index of prism μ=sin2Asin[2(A+D)]
