Under classic physics there is no mechanism you just have to accept it does it, QM is telling you why it does it think about Haroche’s experiment.

As far as I know classical physics recognized the existence of radiation. They may not have understood how it worked, but they certainly knew about it. In fact the Ultraviolet Catastrophe was one of the things that led to the development of QM. They knew all about radiation, and it was pretty well understood. The fact that it was quantized was the only thing they were missing.

C is not the speed of light in a vacuum.
C is the universal speed limit.
