Focal Length of Spherical Mirrors
Chapter-9|Ray Optics and Optical Instrument|NCERT 12th Physics: Focal Length of Spherical Mirrors: We consider a ray AB parallel to principal axis, incident at point B of a spherical mirror(concave or convex) of small aperture. After reflection from the mirror, this ray converges to point F(in case of concave mirror) or appears to diverge from point […]
