Carrier wave with no modulation transports no information.
This shows a strictly monochromatic (single frequency) wave
(red curve)
with no modulation (blue flat line, no markers).
Note how the carriers go towards the PIM-NIM surface but not across it.
Since there is no modulation present, can you see anything
crossing the PIM-NIM surface from left to right? Clearly not.
So this movie cannot represent any signal or information or energy
launched from left and crossing the PIM-NIM surface to right.
One needs a modulated wave so something can go from left to right,
as you will see in the next movie.
