ABSTRACT

This paper discusses about the momenta of photons in dielectric media. It is one of the unsolved problems in physics, especially optics. The problem took shape when, two scientists came up with two theories, mutually contradicting, with both of them supported by opposing experimental data. How can behaviour of light change in different experimental conditions? What have we missed? Shall we zoom in to the quantum level to explain this phenomenon? Or is it possible to explain it classically? I shall try to explain the variation of momentum with the help of curvature of the wave-front of incident light. We will discuss about the properties of curvature dependence of radiation pressure in media with higher refractive indices than vacuum. We will also derive a formula that accounts both for momentum and curvature, and also introduce the notion of ‘Transition Constant’. It will explain the transition between kinetic and canonical momenta of photons in experiments.
