Thin Lenses Placed in Contact
Thin Lenses Placed in Contact - Let two thin lenses L 1 and L 2 of focal lengths f 1 and f 2 be placed in contact so as to have a common principal axis. It is required to find the effective focal length of this combination. Let O be a point object on the principal axis. The ..
Sign Convention for Lenses
Sign Convention for Lenses - Following sign convention is used for measuring various distances during the formation of images by lenses: All distances on the principal axis are measured from the optical center. The distances measured in the direction of incident rays are positiv..
