Magnification of a Lens
MAGNIFICATION OF A LENS
Like spherical mirrors, we have magnification for spherical lenses. Spherical lenses produce magnification and it is defined as the ratio of the height of the image to the height of an object. Magnification is denoted by the letter ‘m’. If height of the object is h and height of the image is h´, the magnification produced by lens is,
Also it is related to the distance of the object (u) and the distance of the image (v) as follows:
If the magnification is greater than 1, then we get an enlarged image. On the other hand, if the magnification is less than 1, then we get a diminished image.
