-Hello,

I would like to start a discussion about a new way to test for the invariance of light speed. Rather than using optics, I suggest using radio waves as the center piece of the experiment. The experiment would still rotate 90 degrees to look for anisotropy, but this experiment would be looking for changes in the radio wavelength. The logic for this is described below. What are your thoughts?

Frequency: ƒ = ⅽ / λ --- It has been observed that electromagnetic radiation travels as a wave through space and its propagation is causally related to the speed of light in both frequency and in wavelength.

ⅽ = ƒ λ --- It is widely accepted that in every case, if frequency of a radio wave is multiplied by the length of the radio wave the result will always be the speed of electromagnetic propagation at 299,792,458 m/s

A logical consequence of the above equation is that if there were a change in c, there would have to be a consequential change in either the frequency or the wavelength or both.

Further logic suggests that if there is an increase in the velocity of c, and if an experimenter can control the frequency, there would have to be a resultant change in the wavelength of the transmission.

Thus, if an experimenter can measure an increase in wavelength, while maintaining the same frequency and without a change in the input voltage of the RF signal, then it must be a result of a change in the velocity of c.
