Light’s Fundamentals

Abstract

Current theory has it that as light passes from one medium to another, that it is the change in velocity that ‘causes’ the light to be refracted entering the new medium at a different angle, also known as the Huygens principle. Evidence however proves this to be in error, since light’s velocity (by common knowledge) changes in the normal as well as by refraction, nor will it refract in the normal.  A change in density affects velocity, and only velocity. While a change in direction is accomplished by angular deviation, by the angle of incidence at which each separate wavelength strikes the surface out of the normal.
