RELATION BETWEEN ‘RADIUS’ AND ‘FOCAL LENGTH’ OF A SPHERICAL MIRROR

Let us consider a parallel beam of light falls on concave and convex mirrors. The law of reflection are applied at each point. The normal to the surface at the point ‘M’ is ‘CM’. After reflection, the ray converges to the point ‘F’ (as in the case of convex mirror). Let incident ray makes an […]
