Energy-sucking Radio Antennas


Posted on Oct 23, 2012

Here's something that has always bugged me: light waves are about 5000 Angstroms in wavelength, while atoms are more like 1 Angstrom across. Atoms are thousands of times smaller than light waves, yet atoms obviously interact very strongly with light. How can they do this? Perhaps they get around the problem by employing Quantum Mechanics (photon-physics rather than EM waves?) There must be some explanation.

After all, when a metal dipole antenna is only one foot long, it certainly cannot absorb much 5000ft-wave radiation. I never encountered a good explanation for this during my physics education. I finally found a couple of physics papers that make things c
