Part 7/8:
The consequences of the speaker's position extend to practical cases such as radio waves and the photoelectric effect. They propose that antennae receive radio waves through magnetic-induced currents rather than through electric fields, fundamentally altering the understanding of how electromagnetic waves are received. The discussion also highlights that the photoelectric effect can be coherent with this model: the changing magnetic fields interact with the surface, generating currents that explain why higher frequency light ejects electrons more rapidly.
