When we evaluate systems that contain thin lenses, several parameters within the system may be of interest to us. At times, the distances that separate the object ( do ) and image ( di ) from a lens at hand are related to the physical dimensions of the lens itself by the Thin-Lens Equation, alsoContinue reading “GEOMETRICAL OPTICS: Object and Image Focal Points and Focal Lengths”

GEOMETRICAL OPTICS: Positive and Negative Sign Conventions
In order for the Thin-Lens Equation and similar derivations to mathematically represent thin-lens systems, sign conventions must be assigned to the physical parameters encountered within optical systems that are modeled. In some circumstances, relationships between the height of an object ( ho ) or image ( hi ) are related to the distances ( doContinue reading “GEOMETRICAL OPTICS: Positive and Negative Sign Conventions”
GEOMETRICAL OPTICS: Thin Lens Equation Derivation
Of all the various equation derivations one may encounter as an introductory physics student, the ones regarding ray diagrams are as counterintuitive as any. Whether a system at hand consists of thin lenses or mirrors, radiant energy is diagrammed as rays for the sake of simplicity. Never, ever forget that these diagrams are grossly oversimplifiedContinue reading “GEOMETRICAL OPTICS: Thin Lens Equation Derivation”
GEOMETRICAL OPTICS: Thin Convex Lenses
Spherical wavefronts of radiation emanate from point sources of light. As the electromagnetic wavefront expands, it carries energy and momentum that become more dispersed as the wavefront gets larger. If the distance between a light source and detector ( such as the human eye ) is infinite, the light detector will intercept a small componentContinue reading “GEOMETRICAL OPTICS: Thin Convex Lenses”
