The equation of refraction at a spherical surface is


 


μ2 / v – μ1 /u = μ2- μ1 /R


 


taking R=∞, show that this equation leads to equation


 


real depth/ apparent depth = μ21

when R is infinite, u r talking abt a glass slab.So,u were correct

when R=infinity,ur actually talking abt a plane interface like in the case of slabs.


(n2/v)-(n1/u)=0


n2/v=n1/u


u/v=n1/n2


as mentioned earlier that a surface with infinite radius will act as a plane interface,'u' corresponds to real depth(object distance) and 'v' corresponds to apparent depth(image distance).Furthur something by infinity is 0.Now check out ur statement.
