WebJan 27, 2024 · Conclusion: A concave mirror has the focal length of 20 cm. Find its radius of curvature. If an object is placed at 30 cm from the mirror, then find the image distance. The focal length, f = 20 cm. Then using the formula {\color {Blue}f=\frac {r} {2}} f = 2r we get the radius of curvature of the concave mirror is, r = 2f. WebA spherical mirror is a mirror which has the shape of a piece cut out of a spherical surface. There are two types of spherical mirrors: concave, and convex. ... The distance along the principal axis from the focus to the vertex is called the focal length of the mirror, and is denoted . Figure 69: Image formation by a concave 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 …
