Focal length of a mirror
WebA 4.00-cm tall light bulb is placed a distance of 45.7 cm from a concave mirror having a focal length of 15.2 cm. Determine the image distance and the image size. Like all … WebSince the focal point is the midpoint of the line segment adjoining the vertex and the center of curvature, the focal length would be one-half the radius of curvature. The focal point is the point in space at which light incident towards the mirror and traveling parallel to the principal axis will meet after reflection.

WebFeb 20, 2024 · A more strongly curved mirror has a shorter focal length and a greater power. Using the law of reflection and some simple trigonometry, it can be shown that the focal length is half the radius of curvature, or \[f = \frac{R}{2} \label{25.8.1},\] where \(R\) is the radius of curvature of a spherical mirror. The smaller the radius of curvature ...
