hence ofcourse it changes according to as wat is d ratio of (ulens/uobject)  ...if its greater dan 1..new f is +ve and hence converging...

if its less dan 1,, new f is -ve and hence diverging

No, the focal lenght is the property of the mirror, not of the medium in what is situated.
the focal lenght = mirror radius / 2
