### Mirror Equation - Formula, Sign conventions, Explanation

1. It is an equation relating object distance and image distance with focal length is known as a mirror equation. It is also known as a mirror formula. In a spherical mirror: The distance between the object and the pole of the mirror is called the object distance (u)
2. 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)
3. Second Formula for Magnification There is another formula of magnification Note : - If magnification (m) is positive , It means image formed is virtual and erect If magnification (m) is negative, It means image formed is real and inverted Questions Example 10.1 - A convex mirror used for rear-view on an automobile has a radius of curvature of 3.00 m
4. Mirror Formula :- Below figure shows the ray diagram of image formation by concave mirror considering three rays. It shows the image A′B′ (real in this case) of an object AB. In the above figure only three rays emanating from the point A are shown but actually an infinite number of rays emanate from any source, in all directions

The mirror formula for a concave mirror is given below. The magnification image formed by a spherical mirror is given by the height of image divided by the height of the object. The formula is given as: 4,21,63 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) Mirror Formula An expression showing the relation between object distance, image distance and focal length of a mirror is called mirror formula. Assumptions and Sign conventions To derive the mirror formula following assumptions and sign conventions are made Mirror formula is relationship that combines image distance,object distance and focal length of the mirror. Expression for mirror formula is 1/u+1/v=1/f Here u=object distance as measured from pole of the mirror and V=image distance and f being the focal length of the mirror

The mirror formula is 1/f = 1/v + 1/u and it is also applicable to a plane mirror. Now, we know that for a plane mirror v = -u Therefore 1/f = -1/u +1/u = 0. Thus f is at infinity Modern mirrors are made by depositing aluminum. But back in the Victorian era aluminum wasn't available and so they made their mirrors using silver metal. Using silver nitrate (available online, or can be made in another wikiHow) you can.. Mirror Formula To do the sums related to the spherical mirrors, the formula used is known as mirror formula. It is used to calculate the focal length, image distance, object distance and also the magnification or any other thing required

Let AB be an object placed on the principal axis of a convex mirror of focal length f. u is the distance between the object and the mirror and v is the distance between the image and the mirror. convex mirror formula But DE = AB and when the aperture is very small EF = PF Spherical Mirror Formula 15,01,891 The Mirror formula explains how object distance (u) and image distance (v) are related to the focal length of a spherical mirror. Object distance is the distance of the object from the pole of the mirror; denoted by the letter u The derivation of the mirror formula or spherical mirror formula is one of the most common formulas in optics. The mirror formula can be termed as the formula in which the relationship between the distance of object represented as 'u' and the distance of the image represented as 'v', and the focal length of the mirror given as 'f' This distance can easily be calculated using the mirror formula. Let's scroll ahead to find more. Suggested Videos . Sign Conventions. The sign convention for spherical mirrors follows a set of rules known as the New Cartesian Sign Convention, as mentioned below: a. The pole (p) of the mirror is taken as the origin We have the mirror equation. (1/v) + (1/u)= (1/f) and the lens equation. (1/v) - (1/u)= (1/f) Where. u =object distance from the mirror/lens. v =image distance from the mirror/lens. f =focal length of the mirror /lens. My doubt is, when we are doing some problems in optics using these equations should we to apply the approved sign conventions.

Mirror Formula An expression showing the relation between object distance, image distance and focal length of a mirror is called the mirror formula. To derive the formula following assumptions and sign conventions are made. The aperture of the mirror is smal more. 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 Spherical Mirror Formula Derivation. The verification of the mirror formula 1 v + 1 u = 1 f is shown below: (Image to be added soon) We will now derive the mirror equation between u, v, and f.

By mirror formula, we have v = - u, i.e. the image distance is equal to the object distance and the image is on the back side of the plane mirror. Hence, the mirror formula is also true for plane mirrors A plain flat mirror would be rated at 1X and one that makes an object 3 times larger would be rated at 3X. For make‐up and shaving mirrors the most common ratings are 3X, 5X, 7X and 10X. There is a formula for the magnification but, unfortunately, it is not always applied correctly. 3) For most users a 3X or a 5X mirror works very well Mirror formula is given below 1/image distance + 1/object distance = 1/focal length Or, 1/v + 1/u = 1/f v = distance of image from mirror u = distance of object from mirror f = focal length of mirror.
