Energy "absorption" Hi, Apologies if I've misinterpreted / mis-read something here (not a physics student - just a general interest). Just hoping to be put straight on something fairly simple: Are atoms / electrons able to interact with waves ie microwave / radio waves? If so, are there waves they are less able to interact with, and is this attributed to the wavelength of the wave vs their EM field size? Do the principles used for radio reception apply on an atomic level too? ie for a receiver, would increasing the EM field strength allow it to pick up wider waves? On an atomic level, can you increase the field strength of an electron? If it is possible, can electrons interact with longer wave types?
