Question

What is the mirror formula? What is magnification by spherical mirrors?

Answer 1

Mirror formula:

1. The mirror formula describes the relationship between the focal length of a spherical mirror and the object distance $\mathrm{u}$ and image distance $\mathrm{v}$.
2. The object distance, represented by the letter $\mathrm{u}$, is the distance between the object and the pole of the mirror.
3. The image distance, represented by the letter $\mathrm{v}$, is the distance between the image and the mirror's pole.
4. The mirror formula is given as $\frac{1}{\mathrm{u}}+\frac{1}{\mathrm{v}}=\frac{1}{\mathrm{f}}$.Here is focal length.

Magnification by spherical mirrors:

1. The increase in image size caused by spherical mirrors in comparison to the size of the object is referred to as magnification.
2. It is written as m and is the height of the image divided by the height of the object.
3. The magnification of a spherical mirror, $\mathrm{m}$, can be represented as $\mathrm{m}=\frac{\mathrm{h}}{\mathrm{h}\text{'}}$. Here, $\mathrm{h}$ is height of image and $\mathrm{h}\text{'}$ is height of object.
