What is Light? An explanation of light and its particle vs wave debate by Jeff Yee.

Light is a small portion of the #electromagnetic wave spectrum that humans can detect with eyes. What is the electromagnetic wave and how is it generated? The answer lies deep within #atoms as particles, like #electrons, vibrate to create everything from radio waves to gamma rays.

This video explores the particle and wave behavior of the #photon that carries #light and these different types of waves, simplifying the explanation of light and the various waves in the electromagnetic spectrum.

A common set back in the model of what light is, is the idea that either light has to be a wave, or a photon has to be a particle, or wav-icle. But, not both. There are many experiments that show that light is a wave in a medium and a photon is a particle that creates a vibration in the medium. The most popular experiment is the Double-slit experiment. The most convincing experiment is spectroscopy, or widening, or dispersion of spectral lines, from radioactive sources that give off photons, or other particles.
GPS studies show, that there is an ether medium gradient around stars, and the Earth; and that the energy of a photon does not change as it climbs up or down a gravity-well. The redshifting and dispersion of the spectral lines shows that as a photon emerges from a radioactive source, within a gravity-well, the spectral lines not only redshift, as the photon emerges into the ether medium, but the spectral lines also show dispersion.
If Einstein were right, or if light were just a photon, or if light was just a wave in a medium, we would see distinct spectral lines, whether redshift, blueshifted, or not shifted. That is what we see from sources from which there is no photon emitted, such as GPS radio sources, or an LED. However when a photon or radiation is emitted, we see a widened of the spectral lines, meaning that as the photon is ejected and emerges from a gravity-well, it emits a frequency based upon the medium density surrounding it. As the photon emerges, the photon meets a decreasing medium density, widening of the wavelength of the energy wave it creates, an increase in the speed of light, and the frequency of vibration in the medium lowers. The result is widening and a redshift of the spectral lines that are created by the photons, as they emerge from the gravity-well. That is Gravitational redshift. This has been shown not to happen with radio signals in GPS, but only with radioactive particles from a gravity well. This is only possible if a photon is a particle and it creates a wave as it travels.
So light from an LED is just a wave W/O a photon, but light from a laser is a photon, or other particle, that emerges into and vibrates the medium.

Your videos are great. Just what physics needs, a reasoned alternative view. Keep them coming!

Why does everyone forget that there are two terms... Electro + magnetic. How did we get to the point that 2 terms became one term? Electro - Magnetic -> Light -> Wave Particle.... Does not computer logically

The problem is you cannot flatten a 3D electro magnetic model into a 2D transverse wave model while ignoring the perpendicular z axis component of the wave and expect to understand the difference in what you observe versus what is actually going on. Just because your eye or detector perceived light as a particle doesn't actually mean it is a particle. That is like me calling a star a particle in the night sky.

Is visible light propagated from the sun to earth? If so, how does it survive the Compton effect? Solar wine density is 5 particles/cm^3, this increases closer to the sun. And such a density defies the idea of visible light propagating thru space

What is actually reflecting an in-wave to push it the opposite direction so that it becomes an out-wave? Is there a shell of somekind, of a spherical form? In your articles I see there is a spring-mass nature to the spacetime fabrick, but I still don't understand how an in-wave is reflected. By which part is it reflected in the lattice structure, because it's just the structure itself, the lattice of granules that is waving, actually?

Thanks

This is not correct.
To see what light actually is take a piece of steel, using a torch, apply heat to a spot, apply heat will impart energy into the atoms, as the energy level of the atoms increases, so will the orbital rates of there electrons, very quickly this rate will reach rate that corresponds to the lower end of the IR spectrum, at which point, the spot in the steel, will begin to radiate heat, if we continue to apply heat, the orbital rate will rise until it reaches a rate that corresponds to the upper end of the IR spectrum which overlaps the lower end of the light spectrum, at which point the spot will begin to glow, thus radiating light, light is the atomic energy wave radiated by the atom, with a wavelength that is within the light spectrum portion of the atomic energy spectrum. I have seen many refer to light energy as being electromagnetic energy, this is false as you can clearly see, electromagnetic energy requires we manipulate the number of electrons in an atom (change the atoms charge or potential).
