Answer 2

Answer:

The relation that is valid for the spherical mirror and the spherical lens are m = f/f-u and m = f-v/f, respectively.

Explanation:

The enlargement of the picture created by spherical mirrors in relation to the size of the object is known as magnification.

It is represented by the symbol m and is equivalent to the image distance to object distance ratio, m = v/u

Focal length (f) is the separation between the focal point (F) and a lens or mirror.

The magnification and focal length of a spherical mirror are related to each other by the equation-

m = f/f-u where f is the focal length and u is the object's distance from the mirror.

It is derived from the mirror formula, 1/f = 1/v + 1/u

While the magnification and focal length of a spherical lens are related to each other by the equation-

m = f-v/f where f is the focal length and v is the image distance from the lens.

It is derived from the lens formula, 1/f = 1/u - 1/v

Thus, The relation that is valid for the spherical mirror and the spherical lens are m = f/f-u and m = f-v/f, respectively.
