When Is a Composite Object a Particle?

A single photon with energy less than the ionization potential– basically anything with a wavelength longer than a couple hundred nanometers, in the deep UV range– might move an electron ... why these composite particles have a de Broglie wavelength ...Physicist suggests speed of light might be slower than thought

This image shows the remnant of Supernova 1987A seen in light ... theorised 80 years ago. Here's a question… how long does it take sunlight to reach Earth? This sounds like a strange question, but think about it. Sunlight travels at the speed of light.- 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 ...

But the picture tells us nothing about the speed of the train ... and particles such as electrons were shown by the de Broglie brothers to have a wavelength when they travel through space. But you might speculate that an electron must have an exact ...The Mystery of Dark Matter Clarified—a Little

That means there’s still hope for a dark horse in the dark matter sweepstakes ... slightly blocking the light they emit. But while planets marginally dim the light of a star, a black hole moving in front of it should have the opposite effect.
