What Is Mirror Equation? Mirror equation is an equation relating object distance and image distance with focal length. It is also known as the mirror formula. In a spherical mirror: The distance between the object and the pole of the mirror is called Object distance (u).
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).
What is Mirror Formula? The Mirror Formula (also referred to as the mirror equation) gives us the relationship between the focal length (f), the distance of the object from the mirror (u) and the distance of the image from the mirror (v). The mirror formula for a concave mirror is given below.
Jun 26, 2024 · The mirror formula connects distances of the object and image from the pole of a mirror and the mirror's focal length. Here is the equation relating these three variables: \frac {1} {f}=\frac {1} {v} + \frac {1} {u} f 1 = v1 + u1. where: f f — Focal length of the mirror: the distance between the principal focus and the pole of the mirror.
Mirror Formula helps us to find: a. Image distance which is represented as ‘v’. b. Object distance which is represented as ‘u’. c. Focal length which is represented as ‘f’. And is written as : 1 v + 1 u = 1 f. This formula is valid for all kinds of spherical mirrors, for all positions of the object.
Apr 16, 2024 · What is Mirror Formula. This formula denotes relationship between. Object Distance (u) Image Distance (v) Focal length (f) Note : - We follow the sign convention for mirrors. In the image, the red text is negative, and blue text is positive. Thus, If Virtual image is formed, v is positive. If Real Image is formed, v is negative.
As far as I know, there are majorly 4 formulae in light: the mirror formula, lens formula and magnification. All three are sign sensitive as in a mirror and lens, each side has a different denotation. Even the power of lens formula is sign sensitive, as it is calculated using focal length of a lens.
The mirror equation expresses the quantitative relationship between the object distance (d o ), the image distance (d i ), and the focal length (f). The equation is stated as follows: The magnification equation relates the ratio of the image distance and object distance to the ratio of the image height (h i) and object height (h o ).
Jan 26, 2023 · We will focus on mirrors as the standard reflective surface, although there are many other surfaces such as a clear lake which can produce a sharp reflective images. Let us start with the most standard mirror which we use in our daily lives. This mirror is known as the plane mirror, simply due to its flat shape.
A formula which gives the relationship between image distance (v), object distance (u) and focal length (f) of a spherical mirror is known as the mirror formula. The mirror formula can be written as : \(\frac{1}{\text { Image distance }}+\frac{1}{\text { Object distance }}\) = \(\frac{1}{\text { Focal length }}\) or \(\frac{1}{v}+\frac{1}{u ...
