Focal Length Of Spherical Concave Mirror at Noah Noriega blog

Focal Length Of Spherical Concave Mirror. Notice that rule 1 means that the radius of curvature of a spherical mirror can be positive or negative. A concave mirror is defined as the spherical mirror whose reflecting surface is curved inwards and follows laws of reflection of light. Convex mirrors diverge light rays and, thus, have a negative focal length. The incident ray is parallel to the optical axis. Figure 2.8 shows a single ray that is reflected by a spherical concave mirror. The image distance \(d_i\) is positive for real images and negative for virtual images. How does the focal length of a mirror relate to the mirror’s radius of curvature? The equation for image formation by rays near the optic axis (paraxial rays) of a mirror has the same form as the thin lens. Following are the ways to obtain the focal length of the concave mirror: The focal length f is positive for concave mirrors and negative for convex mirrors. The focal length \(f\) is positive for concave mirrors and negative for convex mirrors. Focal length is the half of radius of curvature of the spherical mirror. The image distance is positive for real images and negative for virtual. The light rays coming from a distant object can be considered to be parallel to each other. If r is the radius of curvature of the mirror then its focal length will be {\color {blue}f=\frac {r} {2}} f = 2r.
