Spherical Mirrors - 7 Magnification Formula Derivation
WebNow, that all these conventions are clear; let us know move on the mirror formula. 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 : This formula is valid for all kinds of spherical mirrors ... WebFormula used: f = R 2 1 v + 1 u = 1 f Calculation: To calculate the Focal length of the given mirror, substitute the value of Radius of Curvature (R) in f = R 2 We get- f = + 4.00 m 2 = + 2 m Since, 1 v + 1 u = 1 f we can re … WebOct 17, 2024 · Lenses - Derivation of Magnification formula BAIKADI JANARDHAN REDDY 985 subscribers Subscribe 1.1K views 2 years ago In this video I showed the derivation of … cm飛ばし機能
