A short object of
The length of the image is equal to.
The length of the object is = L, object distance is u and focal length = f. To find the length of the image we use the mirror equation. The Length of the object is
The mirror formula or mirror equation specifies the relation between the object and image distance to the focal length of the object.
u is the object distance, v is the image distance and f is the focal length of the object put in the principal axis.
To find the length of the image that is v, we use
Now separating the size of v with respect to the size of the object and focal length
Due to smaller length of the object () let us differentiate the equation with respect to u and v.
Putting equation (2) in (1) we get
Therefore, the length of the image is equal to
