Nothing in this diagram is shown to scale.
The image above shows the sun’s output of radio waves, which have the longest wavelengths, lowest frequencies, and lowest energies of any part of the electromagnetic spectrum.
This image, above, shows the sun’s microwave output.
This next one should be familar. It’s visible light. (Don’t stare at the sun, though.)
Moving on through the spectrum, ultraviolet is next:
After that, x-rays:
And, finally, we arrive at the other side of the spectrum, where the electromagnetic radiation has its shortest wavelengths, and highest frequencies, as well as energy per photon. This is the sun in gamma rays:
Most of these images, all found using Google image-searches, use false colors, of course . . . or you wouldn’t be able to see them!
