What is the relation between the focal length and radius of curvature of a spherical mirror (concave mirror or convex mirror ) ? Calculate the focal length of a sphrical mirror whose radius of curvature is 25 cm.
Write the relationship between focal length and radius of curvature.
What is the relation between focal length and radius of curvature of a concave mirror? Does the same relation hold for a covcave mirror?
The focal length f is related to the radius of curvature r of the spherical convex mirror by
A LASER source placed between two concave mirrors sends light rays as shown in the figure. If PQ and RS are parallel to the principal axis, determine the focal lengths and radius of curvatures of both the mirrors.
