the equations for spherical mirrors and thin lenses are the same only in RP sign convention.
In recent ( co-ordinate) sign convention for mirror its as u gave , but for lenses it is ( 1/ v ) - ( 1 / u ) = 1 / f |

) is equal to the angle of reflection (
) as measured from the normal to the reflecting surface.
) and angles of refraction (
) for a wave impinging on an interface between two media with different indices of refraction (
, 
)
) is a ratio of speeds that compares the speed of light in a medium (
) to the speed of light in a vacuum (
). The ratio can also be defined in terms of the wavelength (
) of light in different materials.
)is the certain angle of incidence at a boundary between two materials where the angle of refraction equals 90°. This formula is used to calculate that angle, and works only if
