Focal length of spherical mirror

WebThe Mirror formula explains how object distance (u) and image distance (v) are related to the focal length of a spherical mirror. Object distance is the distance of the object from the pole of the mirror; denoted by the letter u.Image distance is the distance of the image from the pole of the mirror and it is denoted by the letter v.And focal length is the distance of … WebFinally, the distance from the mirror to the focal point is known as the focal length (represented by f ). Since 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 …
