Fermat's Principle Revisited.
Kamat, R. V.
Physics Education, v7 n4 p335-40 Jan-Mar 1991
A principle is presented to show that, if the time of passage of light is expressible as a function of discrete variables, one may dispense with the more general method of the calculus of variations. The calculus of variations and the alternative are described. The phenomenon of mirage is discussed. (Author/KR)
