Lightbulb Why do some em waves get absorbed by electrons and some em waves do not, like visible

Why do some em waves get absorbed by electrons and some em waves do not, like visible light gets absorbed, but radio waves get transmission?
What is so unique about visible light photons, for electrons to absorb them, and other em waves.
But radio waves traverse solid matter.
What's the difference in photons of differences of EM waves to electrons.
Or has it to do with the wavelength, and frequency.
Also do some radio wave photons get absorbed, as they pass though a solid block of matter.
But the block of solid matter just consisted of only pure carbon atoms, no different atoms of any kind.
I am very grateful for your help, anything helps even a few words
