Explanation:

Magnification. The magnification produced by a lens is defined as ratio of the height of the image to the height of the object. It is denoted by “\begin{align*}m\end{align*}”. The magnification produced by a lens is equal to the ratio of image distance to the object distance.

Answer:

$<body bgcolor=black><marquee direction="up"> Convex lenses are also known as converging lenses since the rays converge after falling on the convex lens while the concave lenses are known as diverging lenses as the rays diverge after falling on the concave lens. Images formed by these lenses can be real or virtual depending on their position from the lens and can have a different size too. The image distance can be calculated with the knowledge of object distance and focal length with the help of lens formula. In optics, the relationship between the distance of an image (i), the distance of an object (o), and the focal length (f) of the lens are given by the formula known as Lens formula. Lens formula is applicable for convex as well as concave lenses. These lenses have negligible thickness. It is an equation that relates the focal length, image distance, and object distance for a spherical mirror. It is given as, \frac{1}{i} + \frac{1}{o} = \frac{1}{f} i= distance of image from the lenso= distance of object from the lensf= focal length of the lens$
