Let, 
Refractive index of air and water be n1 and n2 respectively.
Also, real and apparent depth be u and v respectively.
Now, 
n subscript 2 over n subscript 1 equals u over v i. e. comma space v equals u cross times n subscript 1 over n subscript 2... left parenthesis 1 right parenthesis N o w comma V space equals space pi R squared u o r space increment V space equals space space pi R squared increment u S u b s t i t u t i n g space t h i s space i n space e q u a t i o n space left parenthesis 1 right parenthesis increment v equals fraction numerator increment V over denominator space pi R squared end fraction cross times n subscript 1 over n subscript 2 equals space space x pi R squared cross times n subscript 1 over n subscript 2
