Electrons discover their individuality

"This special interference pattern is no longer observed if the speed of the emitted electron exceeds a particular value," says Uwe Becker. The de Broglie wavelength then decreases to below the distance between the nitrogen atoms and the electron can now ...What is the Big Bang all about?

And light — a form of massless radiation — behaved differently. As the Universe expands, the number of photons stays the same, and so the energy density dilutes similarly to matter. But for radiation, its energy is defined by its wavelength ...- French physicist Louis Victor Pierre Raymond de Broglie ... any speed. Light did not have rest mass: it is either moving at a certain speed (which may vary depending on the environment), or does not exist. By analogy with the relation between the ...
