Question

solve this question and gave me solution also answer is √3/√2

Answer 1

2.449448447 ............

Answer 2

refractive index =sinB/sinA
                        
                          =(root(3)/2)/1/root2   (1/root 2=root(2)/2

                           =(root(3)/2)/root(2)/2

                            =root(3)/root(2)
