Focal length given radius
WebRadius of Curvature 2 = 6 cm. We know the focal length of a thin lens is given by 1/f = (n - 1) * (1/R1 - 1/R2) Substituting the inputs in the above formula we have the equation as follows. 1/f = (1.5-1)* (1/4-1/6) Simplifying further we get the focal length f = 24 cm. Therefore, the focal length of thin lens for given parameters is 24 cm. WebApr 7, 2024 · By using the formula below, the focal length f of the convex mirror can be calculated. F = R 2. Where, R-Radius of curvature. A mirror with a reflecting surface facing outwards is a Convex mirror, whereas a mirror with a reflecting surface facing inwards is a Concave mirror.
