Prism Rainbow

I'm trying to imagine what happens to light as it passes through a prism. It is thought that the speed of light 'slows down' inside the prism. As discussed previously, the speed of light must be the same inside, and outside the prism, because the colours of the visible spectrum maintain their wavelength and frequencies. If either the frequency or wavelength or speed of light were to change, then so would the substance of the light. This plainly does not happen. The angles of refraction infer that the same violet light inside the prism is the exact same one which exits the prism. Rather than the speed of light slowing down, perhaps it is the medium through which light travels that is being stretched.

Before Einstein introduced us to the entity that is spacetime, most scientists were familiar with the idea that electromagnetic waves propagated through an 'invisible' medium - the aether. Some have referred to the aether as a latent magnetic field, which becomes excited by matter. EMR was thought to travel through the aether, much like sound waves need to travel through molecules in the air.

I am only in the early stages of learning about the aether, so don't accept what I am about to say as gospel, but it would appear that the aether could quite easily fill the boots of spacetime. That is, where before we had a mass, such as a planet, forming a huge dent on the blanket of spacetime, we can now think of it as a blanket of aether. Whereas the speed of light was once bent by gravitational forces, it is now bent by surface tension in the aether. This all obviously needs work, but it does have a parallel with what is happening to the light inside the prism.

I could explain this a bit better with a diagram, but I plain don't know how to, so please bear with me. Draw a U-shape. Now draw a triangle shape with the U in the centre. The triangle is your prism. A simple line to denote white light moving from outside to inside the prism is enough. Once inside, the white light is dispersed, so we shall draw frantic shortwave frequencies to denote the violet end of the spectrum - these travel not in a straight line through the prism, but follow the shape of the U - until you are out the other side of the prism. Okay, so next-up is red light moving through the prism and following the shape of the U. Red has a longer wavelength, and lower frequency than violet, and it travels much faster around the U than the higher frequencies of violet.

The 'U' represents the aether field. I am proposing that inside the prism the aether field is being distorted. This would explain why the shorter wavelengths of violet appear to travel faster inside the prism than the longer wavelengths of red. It's an illusion. Violet does not travel faster than red, it simply takes longer to cover the same distance. It would also imply that the higher frequencies are more affected by a distortion in the aether field. The prism has created a 'sink' in the aether field. The aether field is sometimes referred to as cold energy (and electromagnetim as heat energy). So what we have is a cold energy sink. A cold energy sink can perhaps, be thought of as a storage space of energy. How can we maximise, and tap into this free energy?
