What is Mirror Equation?
Mirror Equation is a formula that provides the relationship between the focal length, image distance, and object distance of any spherical mirror. The Mirror Equation is based on the principles of reflection and is given by
1/f = 1/v + 1/u
Where,
- f is the focal length of the mirror,
- v is the image distance i.e., distance of the image from the mirror, and
- u is the object distance i.e., distance of the object from the mirror.
Derive Mirror Equation
We can learn the proof of this formula in the article: Derivation of Mirror Formula
Mirror Magnification Equation
The magnification formula for mirrors relates the size and orientation of an object to the size and orientation of its image formed by a mirror. For mirrors magnification formula is given as:
M = – v/u
Where,
- M is the magnification,
- v is the image distance (distance of the image from the mirror), and
- u is the object distance (distance of the object from the mirror).
Mirror Equation
Mirror Equation in Physics is the equation for mirrors that provides the relation between the distance of the object and the image, as well as its focal length. Mirror Equation is helpful in determining object position, image position or focal length given that two of the parameters are given. In optics, which is the branch of science that deals with the study of light and its interactions with various materials and optical elements, mirrors are used in various instruments for various purposes. Thus, understanding the relationship between the focal length of the mirror and the distance between the object and the image from the mirror is very important.
In this article, we will explore the concept of the Mirror Equation in detail, Mirror Equation Proof, and Mirror Equation for Magnification with various types of mirrors as well. So, let’s start learning about the concept of Mirror Equations.
