There many uncertainties regarding the nature of EMR, and light in particular. Conventional Science generally acknowledges that EMR energy is delivered in photon packages, but is decidedly vague as to the physical form of photons in terms of the number of wavelengths involved, and whether they have a particle or a wave-like form. There is general acknowledgement that light has wave—particle duality, but the cross-over point between the two forms is ill-defined. As the term ‘electromagnetic radiation’ (i.e. EMR) suggests, Conventional Science considers that EMR consists of electromagnetic waves consisting of wave-like pressure-pulses of electromagnetic energy and momentum moving at the speed of light. However, such electromagnetic pressure-pulses need some type of substrate, commonly referred to as aether, to sustain them across the vast distances of virtually empty Space. However, all of the many well-publicised science-based attempts to prove the existence of aether have failed dismally, and so the mystery continues as to how electromagnetic waves can sustain themselves through Space.This paper throws new light on the nature, form and generation of all forms of EMR, but for light in particular. Firstly, it distinguishes between photonic and mon-photonic EMR, and puts forward a physical structure for photonic EMR (that includes visible light) that means that observed particle-wave duality characteristics of light would be expected rather than considered to be enigmatic. As well as addressing a wide range of light-related topics such as the refraction of light passing through different transparent media; plane, circular and elliptically polarised light; the chromatic dispersion of light; and exotic forms of light such as optical vortex light, the model put forward does not require aether for EMR to travel through Space. It is truly be a case of ‘light as you have never seen it before’ because it presents clear feasible explanations of light-related phenomena that have previously been unaddressed, or only partly and poorly addressed. Let there be light.
