In an experiment on photoelectric effect, the slope of the cut-off voltage versus frequency of incident light ... is the de Broglie wavelength of (a) a bullet of mass 0.040 kg travelling at the speed of 1.0 km/s, (b) a ball of mass 0.060 kg moving at ...And Let There Be "Molecules" of Light

It is an area around a moving electric ... that the energy of the electron depends on the wavelength of light. Schrodinger studied that light was coherent. This proves that light has the property of superposition. De Broglie used the concept of frequency ...On the Quantum Mechanics of Electrons in the Brain; Free Will

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 ...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.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 ...
