There is no maximum wavelength.

Lowest energy is at lowest frequency, i.e. longest wave length.
When you shorten the wave length, you increase the amplitude.
The product of the wave's frequency and the wave's wave length is equal to the speed of propagation of the wave.

Radio waves are the electromagnetic waves with longest wavelength.
red Type your answer here...
first we must ask our selves do these waves really exist?
Red ... ;)
Radio waves have the longest wavelengths.
