## Speed and Frequency The current fixed ideas about space and time come from a matter-centric viewpoint. Einstein’s Theory of Relativity is formed by looking at “light” through a mind conditioned by matter.

The concept of speed exists only when we consider the units of space and time to be fixed. When these units are not fixed we do not have a proper concept of speed. The theory of relativity talks about length contraction and time dilation as we approach the “speed of light”. This means that the units of space and time are not fixed for light.

#### The concept of speed does not apply to light. Light has no speed.

The experimental determination of “speed of light” uses fixed units of space and time. What it is actually determining is the speed of matter relative to light.

#### The “speed of light” is actually the speed of matter relative to light.

Einstein’s theory of relativity actually provides us with the realization that the units of space and time are fixed for matter only. They are not fixed for electromagnetic phenomenon, such as, light.

Light simply has a constant “wavelength to period” ratio, which we may represent as the “speed of light”. The wavelength and period for light vary according to its frequency. This may be the reason why space and time units are not fixed for light. The parameter that is consistent for electromagnetic phenomenon then is frequency.

#### The concept of “frequency” is appropriate to electromagnetic phenomena rather than the concept of “speed”.

In case of matter, the wavelengths and periods do not exist. The equivalent de Broglie wavelength and period do exist and their ratio is still ‘c’. But because they are infinitesimal the variation in them does not affect the fixed units of space and time used for matter.

#### The concept of “speed” is limited to matter only.

Matter contains the “speed of light” within itself as infinitesimal wavelength to infinitesimal period ratio. It can never attain the “speed of light” relative to other matter because of its property of inertia.

1:1, wavelength to period, is that what you are saying?

• vinaire  On March 27, 2016 at 12:41 PM

Yes. One wavelength to one period. Please note that the units are different. This “wavelength to period ratio” happens to be a constant. This constant is the famous ‘c’ called the “speed of light” by Einstein and others.

λ/t = c (speed of light)

In the diagram you posted, it looks like 1:1. I probably don’t understand what you mean.

• vinaire  On March 27, 2016 at 3:45 PM

Yes. It is 1 (wavelength): 1 (period). Please don’t forget the different units.
