WebJun 6, 2024 · focal length: [noun] the distance of a focus from the surface of a lens or curved mirror. WebMirror formula is given as: 1 f = 1 v + 1 u. From the above equation, we get the focal length as: f = u v u + v. Where, f is the focal length of a concave mirror. u is the distance of object needle from the pole of the mirror. v is the distance of image needle from the pole of the mirror. The value of f will be negative.
