The mirror formula is applicable for both plane mirrors and spherical mirrors convex and concave mirrors.

Physics formula mirror. 03092018 First understand the sign rules of the convex mirror. The equation is stated as follows. If the object is placed between focal.

This formula denotes relationship between. - We follow the sign convention for mirrors. The sign rules for the convex mirror Object distance do If an object is in the front of a mirror surface which reflecting light where the light passes through the object then the object distance do is positive.

Mirror Formula for Concave Mirror when Virtual Image is formed When an object is placed between the pole and the focus of a concave mirror erect and enlarges image formed behind the mirror as shown in figure. Object Distance u Image Distance v Focal length f Note. Assumptions and Sign conventions To derive the mirror formula following assumptions and sign conventions are made.

This equation known as the Equation of Curved Mirrors is. V image distance from the mirrorlens. S do object distance s di image distance h P P object height h Q Q.

04052018 We have the mirror equation. 1f 1di 1do. The mirror equation frac1vfrac1ufrac1f holds good for concave mirrors as well as convex mirrors.

The radius of curvature of a convex mirror used for rearview on a car is 400 m. Ray coming from the center of curvature turn back on itself. 29062021 Equation of Curved Mirrors.

12092018 Lets explore the mirror formula 1f 1v1u and see how to locate images without drawing any ray diagrams. Ray hits the mirror at vertex it reflects with the same angle it does with principal axis. 1v 1u 1f and the lens equation.

A ray of light starting from the end point A of the object and moving parallel to the principal axis strikes the mirror at the point E. In other words if the object image and focal point of the mirror are located in front of the mirror like concave mirrors we take them positive. If they are located behind the mirror like convex mirrors.

The aperture of the mirror is small. 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. U object distance from the mirrorlens.

Rays coming parallel to the principal axis pass from the focal point. In this equation we take the quantities positive if they in front of the mirror. To obtain this type of numerical information it is necessary to use the Mirror Equation and the Magnification Equation.

Mirror Equation for concave mirror and Mirror Equation for a convex mirror. And focal length focus F which allows us to determine the position of image without having need for drawings. The mirror equation expresses the quantitative relationship between the object distance do the image distance di and the focal length f.

Draw LN perpendicular on the principle axis. There is an equation that provides the numerical relationship between the objects distance d o image distance d. 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.

To obtain this type of numerical information it is necessary to use the Mirror Equation and the Magnification Equation. It is reflected at E and passes through the principal focus F. F focal length of the mirror lens.

31082018 The equation of concave mirror. If the location of the bus is 6 meters from this mirror find the position of the image. In this video we will learn the mirror equation and how to find the height and distance of an image.

Physics Formulas OpticsCheat sheet In concave mirrors. 18122016 Concave mirror formula To derive concave mirror formula consider fig. Rays coming from the focal point travel parallel to the principal axis.

An expression showing the relation between object distance image distance and focal length of a mirror is called mirror formula. Now Δ s NLF and ABF are similar therefore A B N L A F N F. 23042020 What is Mirror Formula.

The magnification equation. Hiii This is the mirror formula 1f1v1u Where Uobject distance Vimage distance and F focal length. My doubt is when we are doing some problems in optics using these equations should we to apply the approved sign conventions.

144 where an object OA is placed in front of a concave mirror. Example of Mirror Equation. 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. On the figure below two beams of light are drawn to the concave mirror and the concave mirror reflects the beam of light.
