Focal length of spherical mirror
WebHowever, as discussed above, in the small-angle approximation, the focal length of a spherical mirror is one-half the radius of curvature of the mirror, or f = R / 2. Inserting … WebHence, the focal length f is given by: f = y + x tan2θ. Using the identity tan2θ = 2tanθ 1−tan2 θ, it follows that: f = y + x(1−tan2 θ) 2tanθ. (1) 1. 2. The spherical mirror For a spherical mirror, the curve shown above is part of a circle of radius r. Moreover, C is the center of the circle, since the line segment CP is perpendicular ...
