WebApr 7, 2024 · The distance of the principal focus from the pole of the mirror is known as the focal length. The expression which gives us the relation between these three quantities is called the spherical mirror formula, which is given by: 1 v + 1 u = 1 f The mirror formula is applicable for all spherical mirrors for any possible position of the object.
WebNov 1, 2024 · A mirror's radius of curvature is the radius of the sphere it is a part of. The focal length, f f, of a mirror is always half of its radius of curvature, r r: \quad f = \frac {r} {2} f = 2r Hence, we can also write the mirror equation as follows: \quad \frac {2} {r}=\frac {1} {v} + \frac {1} {u} r2 = v1 + u1 chrome password インポートWebA 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’.
