Lens Formula And Magnification Formula With Numericals Class 10 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. As a demonstration of the effectiveness of the mirror equation and magnification equation, consider the following example problem and its solution. example problem #1 a 4.00 cm tall light bulb is placed a distance of 45.7 cm from a concave mirror having a focal length of 15.2 cm. determine the image distance and the image size.
Mirror Formula With Solved Numericals Class 10 Teachoo R is the radius of curvature of the spherical mirror; the above formula is valid under all situations for all types of (concave and convex) and for all object positions. you may also want to check out these topics given below! refraction of light; reflection of light; magnification; derivation of lens formula or mirror equation; spherical mirrors. Teacher support [bl] [ol] [al] review the lens mirror equation from the reflection section. review the terms focal point, focal length, object distance, image distance, concave, convex, converging, and diverging from the reflection section. We can find the areal magnification using the distances of the object and the image from the pole of a mirror. the areal magnification formula for mirrors in terms of v v and u u is: m \mathrm {areal} = \frac {v²} {u²} mareal = u²v². this mirror equation calculator determines both linear and areal magnification for you. Both the mirror equation and the magnification equation also apply to lenses. however, when dealing with lenses, the mirror equation is renamed the lens maker's equation. the lens maker's equation is 1 f = 1 v − 1 u; the magnification produced by a lens is defined as the ratio of the height of the image to the height of the object. m = h i h o.
What Is Lens Formula Calculating Magnification Power Lens We can find the areal magnification using the distances of the object and the image from the pole of a mirror. the areal magnification formula for mirrors in terms of v v and u u is: m \mathrm {areal} = \frac {v²} {u²} mareal = u²v². this mirror equation calculator determines both linear and areal magnification for you.

The three lenses all have different refractive indices, all radii of curvature are different, the whole thing is immersed in water, the last surface is a mirror, and the object is a virtual object. perhaps you are asked to find the image. or you may be told where the image is and asked to find one of the radii of curvature, or one of the. Further information about the sign conventions for the variables in the mirror equation and the magnification equation can be found in lesson 3. from the calculations in this problem it can be concluded that if a 4.0 cm tall object is placed 35.5 cm from a convex mirror having a focal length of 12.2 cm, then the image will be upright, 1.02 cm.
