Software for Fermat's Principle and Lenses
Mihas, Pavlos
Physics Education, v47 n3 p313-320 May 2012
Fermat's principle is considered as a unifying concept. It is usually presented erroneously as a "least time principle". In this paper we present some software that shows cases of maxima and minima and the application of Fermat's principle to the problem of focusing in lenses. (Contains 12 figures.)
