Question

Define the magnification produced by a lens. Explain it in brief.​

Answer 1

Answer:

Explanation:

The magnification produced by a lens is defined as ratio of the height of the image to the height of the object. The magnification produced by a lens is equal to the ratio of image distance to the object distance.

Answer 2

‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎‎ ‎ ‎Magnification Of A Lens

• Spherical lensed 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 $\sf m$ Height of the object is $\sf h$and height of an image is $\sf h'$, the magnification produced by lens is

‎$\longrightarrow \sf m = \dfrac{\textsf{height of the image}}{\textsf{height of the object}}= \sf \dfrac{h'}{h}$

• Also it is related to the distance of the object $\sf (u)$ and the distance of the image $\sf (v)$ as follows :

‎$\longrightarrow \sf m = \dfrac{\textsf{Distance of the image }}{\textsf{Distance of the object}}= \sf \dfrac{u}{v}$

• 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.
