A parallel beam falls on solid glass sphere of radius R and refractive index `mu`. What is the distance of final image after refractioin from two surfaces of sphere? What is the condition for the image to be real?

A

`(R(mu-2))/(2(mu -1))` from 2nd surface , `mu gt 2`

B

`(R(2-mu))/(2((mu - 1)) ` from 2nd surface , `mu lt 2`

C

`(R(mu - 1))/((2 -mu))` from 2nd surface , `mu lt 2`

D

`R/2 ((mu+2)/(mu+1))` from 2nd surface , `mu lt 2` for any value of `mu`
