A mirror formula can be defined as the formula which gives the relationship between the distance of object 'u', the distance of image 'v', and the focal length of the mirror 'f'.

Magnification In general terms, it can be said that how big or small the image appears with respect to the object is called magnification of the object. It is represented as the ratio of the height of the image to the ratio of the height of the object. Magnification is denoted as the letter 'm'.

Convex mirrors are used inside the buildings, They are also used in making lenses of sunglasses, They are used in the magnifying glass, They are used in securities and they are used in telescopes.
