The mirror equation expresses the quantitative relationship between the object distance (do), the image distance (di), 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 … The mirror … Calculation of Focal length, Image distance and Object distance are made easier using this mirror equation calculator. The mirror equation \(\frac{1}{v}+\frac{1}{u}=\frac{1}{f}\) holds good for concave mirrors as well as convex mirrors. The mirror formula derivation is provided here so that students can understand the concept of the topic in a better way. The radius of curvature of a convex mirror used for rearview on a car is 4.00 m. Example of Mirror Equation. The equation is stated as follows: 1/f = 1/di + 1/do My Account Mirror Equation for concave mirror and Mirror Equation for a convex mirror. To obtain this type of numerical information, it is necessary to use the Mirror Equation and the Magnification Equation. The mirror equation expresses the quantitative relationship between the object distance (d o), the image distance (d i), and the focal length (f). 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’. Formula : Where , f - Focal length, d i - Image distance, d 0 - Object distance. 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. Mirror Equation Formula Where R is the radius of curvature f is the focal length O is the object distance I is the image distance To link to this Mirror Equation Calculator page, copy the following code to your site: The mirror formula is applicable for both, plane mirrors and spherical mirrors (convex and concave mirrors).
