Classical Model of Light Transmission in Optical Media: A Descriptive Study


The goal of this work is to use well-known Classical Physics to thoroughly explain the specific mechanism underlying the observed Fresnel Dragging of light in an experiment like the Fizeau experiment of 1851. The original mathematical approach used to analyse the Fizeau experiment, which discovered the relative speed of light in a moving medium in 1851, assumes that light travels through water in a smooth continuous flow at a slower rate than light travels through a vacuum (relative to the water). As a result, it is believed that the velocity vectors of the water and light may be easily summed. Light, on the other hand, is transmitted through optical media such as water through a continuous process of charge excitation (semi-absorption) and re-emission by the water molecules; despite this, it travels at the speed of light between them (in a vacuum). As a result, the mathematics behind Fresnel dragging must be rewritten such that it can be explained using classical physics, allowing the entire process to be fully understood.
