How do you find photons

Photons obey the laws of quantum mechanics, and so their behavior has both wave-like and particle-like aspects. When a photon is detected by a measuring instrument, it is registered as a single, particulate unit. However, the probability of detecting a photon is calculated by equations that describe waves. This combination of aspects is known as wave–particle duality. For example, the probability distribution for the location at which a photon might be detected displays clearly w… WebMar 27, 2024 · To calculate the energy of a photon, follow these easy steps: If you know the wavelength, calculate the frequency with the following formula: f =c/ λ where c is the speed of light, f...

WebMathematically the photon (or electron for that matter) as a building block in QED can be treated pointlike and without any wavelength, but real world photons are more complicated quantum states with both "width" and wavelength. I … WebTo summarize, photons ARE particles that just show wave behaviour due to us having to describe them as wave functions due to uncertainty of their position. At least this is what I gather after reading QED from Feynman, but I won't pretend to understand anything (Neither did Feynman.) ( 22 votes) Upvote Flag Show more... Bryan Baker 7 years ago At WebFeb 15, 2024 · While photons normally have no mass and travel at 300,000 kilometers per second (the speed of light), the researchers found that the bound photons actually acquired a fraction of an electron’s mass.
