How big is a photon
Webλ = c / f 2 (1) Using Equation (1), we can now choose a Δ v close to the velocity of light c where the photon wavelength ( λ = c / f2) is much smaller than the size of a neutron. With such a short wavelength we can then pass the photon through a hole diameter of 1 neutron = 1.6 × 10 −15 m with high transmission and negligible diffraction. WebAnswer (1 of 4): Infinitely smaller… To the point they don’t exist at all… They’re said to be single frequency ‘sine’ waves, but no one seems to understand that there are no ‘sine’ waves in any spectrum, including of course the EM spectrum. So photons cannot play a …

WebAnyway, if there's an uncertainty of one hertz then the position has an uncertainty of 150 thousand km. Yeah that doesn't really mean anything. You could say a photon is bigger than its Schwarzschild radius. That would be 2G hbar/c 4 , so for an optical energy photon that's about 10 -63 meters. 37. WebA photon is a type of elementary particle that primarily acts as a carrier of energy. An electron is a subatomic particle that is present in all atoms. A photon has no charge. It possesses a negative charge of magnitude 1.62 × 10 −19 coulomb. It has no rest mass. An electron has a mass of 9.19 × 10 -31 kilograms.
