Question

the angle of minimum deviation measured with a prism is 30 degree and the angle of prism is 60 degrre. find the refractive index of the material of the prism​

Answer 1

Answer:

The refractive index of prism material is given by ,

                   n=sin2Asin(2A+δm)

Given , δm=30o,A=60o

Hence ,       n=sin260sin(260+30)

or                n=sin30sin(290)

or                n=sin30sin45   

or                n=2121

or                n=2      

Hope this helped you....
