Question

what is the derivation of formula by curved mirrors
say correct answer​

Answer 1

Answer:

Suppose an object is placed u cm in front of a spherical mirror of focal length f such that the image is formed v cm from the mirror, then u, v and f are related by the equation; 1/f= 1/u + 1/v. This equation is referred to as the mirror formula.

Answer 2

Explanation:

The derivation of the mirror formula is one of the most common questions asked in various board examinations as well as competitive examinations. A mirror formula can be defined as the formula which gives the relationship between the distance of object ‘u’, the distance of image ‘v’, and the focal length of the mirror ‘f’. The mirror formula is applicable for both, plane mirrors and spherical mirrors (convex and concave mirrors). The mirror formula derivation is provided here so that students can understand the concept of the topic in a better way. The mirror formula is written as:

1/f=1/v+1/u
