If you closely notice you will observe that their products are always equal to the wave speed.
Speed (of a wave) = frequency x wavelength
It isn't clear what type of wave you are talking about. If you mean electromagnetic waves, the answer is "radio waves".

I am not entirely sure what you mean; multiplying one frequency by another doesn't seem to make much sense, physically - especially considering that the units, such as cycles/second or cycles/hour, are quite arbitrary, and you would get different results if you use different units.
A higher frequency means a shorter wavelength, and a lower frequency means a longer wavelength.
Speed (of a wave) = frequency x wavelength
The frequencies and wavelenghts are different.

Yes. Sound waves have different frequencies which cause them to be louder/softer/higher/lower.Light waves have different frequencies too. The shorter the distance between the wavelenghts the darker the color. White light (the normal light the sun gives) is all of the colors together
Assuming the products are created from a dataset which contains each value once or more times by multiplying the each value by its frequency in the dataset, then the result of sum of products (of values by their frequencies) divided by sum of frequencies is the mean average of the all the values in the dataset.
The tone frequencies, are selected such that harmonics and intermodulation products will not cause an unreliable signal. No frequency is a multiple of another, the difference between any two frequencies does not equal any of the frequencies, and the sum of any two frequencies does not equal any of the frequencies.
Speed (of a wave) = frequency x wavelength
No, because of the wavelenghts. Those do not correspond to being on the Moon. Except: if you can make special FM wavelenghts.
A higher frequency means a shorter wavelength, and a lower frequency means a longer wavelength.

Lemons Are Yellow Because Their Skins Absorb All Wavelenghts Of Visible Light Except For The Wavelenghts Corresponding To The Colour we Know As Yellow.
