The formula connecting $u, v$ and $f$ for a spherical mirror $\frac{1}{u} + \frac{1}{v} = \frac{1}{f}$ is valid only for mirrors of small apertures where the size of aperture is very small as compared to the radius of curvature of the mirror. Laws of mirror are valid for plane as well as large spherical surfaces. The laws of reflection are valid when ever the light is reflected.
