Still waiting for an explanation of how to vibrate a cone at 20,000 Hz using the same amount of energy as it takes to vibrate the cone at 40 Hz.
Also, an explanation of how high-frequency radiation has greater penetrative power than low-frequency radiation without having more energy. Technicians should be using AM radio waves to examine teeth and bones!
What a bunch of morons.

I think your problem with this concept is that you have confused intensity with energy. The language of physics is a bit more precise than everyday speech. Intensity varies as the square of frequency and is the time-averaged POWER transferred per area through a region in space. Power is work done per second and energy is the capacity to do work. I think you are using intensity interchangeably with energy.
I do find it curious that you think that this site is the proper forum to answer your questions on physics and even more curious that you resort to slurs and call others "a bunch of morons" when you are the one who lacks the the knowledge. Lack of knowledge is not lack of intelligence and no one called you a moron.

If we are talking about waves through a medium like air or water it is the volume of the waveform which is directly linked to the energy it carries.
If you think about it the volume of the wave contains actual molecules (air or water or whatever) which have to be physically moved and this requires energy.
So if you use a 2D representation (think drawing of a sine for example) it is the area covered by that waveform which represents the energy of it.
Electromagnetic waves are in the subatomic region so there are no actual molecules or atoms (ie nothing with a real physical weight) which move. Completely different ballgame as only a (nearly) massless particle like a photon or electron moves through otherwise empty space.
