Answer 1

Answer:

The relation is tani =  n

Explanation:

                From the diagram(it is attached),

                     r+R + 90 = 180

                       r+R = 90 -------(1)

                          also i=R(angle of reflection)

                         r= angle of refraction

                       (1)=>   r+i = 90

                                   r = 90-i---------(2)

                           sini/sinr = refractive index(n)

                         from (2)

                               sini / sin(90-i) = n

                               sini / cosi = n

                                      tani = n
