I was a sonar tech in the US Navy. In order to have a frequency, you have to know how many cycles per second the object is at. Everything has it's on frequency, that much is true, but the bottom line for a frequency is time itself.
1 cycle per second = 1 hertz
In other words you have to have cycles to have frequencies. There are no frequencies without cycles. Cycles determines wavelengths. The lower the frequency, the shorter the wavelength, the higher the frequency the longer the wavelength. Next you need a medium for those wavelengths to travel like air, water , space and ground. Each one has it's own set of hurdles, for air it's the curvature of the earth , for water it is temperature and salinity, for space it is gas and bodies, for the ground it is density of land mass. These add more variables to the equation.
Lets say there is a radio station broadcasting in Germany, and you live in the US, you will be able to hear the station by using a shortwave radio, if using a fm radio you will not hear it, because the wavelengths are different. The shorter or smaller the wavelength the further the wave will travel, the longer or higher the wavelength the less it will travel.
Frequencies are not independant of each other. For example you have a fishing boat on the waters surface, the frequency of the propellers is 50 hz (50 cycles per second). The closer the source the more harmonics of that frequency, you will see..You will see the same signature of 50hz, repeated at 100hz, 150hz, etc....The further away the less of the harmonics you will see. It's called Doppler. As sound approaches your position (if you stand still) it will appear to get louder and louder, as sound moves away from you it will appear to get less and less noisey. Same holds true with light. The frequency of the propellers didn't change, it was the aspect from which you heard the source change (approaching or departing).
To use your analogy of the table. The table has a frequency. It is of visible light. It lets off wavelengths of visible light . In order to let off a wavelength, it has to have a cycle to determine the size of the wavelength (as stated above).
I think the problem that people run into is that they think what they don't observe as reality right now, has to be totally different then that reality that currently exists. In other words going to the opposite end of the spectrum with specualtion or theory only without realizing that there is a step in between that still needs to be observed and proved.
