A line would have a direction in the X and Y coordinates — 3 inches left and 4 inches up, for ... WebApr 18, 2024 · Depends on the photon. It’s like asking what the width of an ordinary particle’s wavefunction is. Sometimes it’s bigger and sometimes it’s smaller. Some sources, such as lasers, emit photons with very long coherence lengths. For instance, the laser in your CD player probably emits wavetrains with lengths of ~10 cm.

WebJul 4, 2016 · If you ask “how big an electron should be” quantum mechanics has an answer. You can guess that an electron should be big enough so that the energy in the electric field is equivalent to the rest mass of the electron (0.511 MeV). If the electron was some sort of charged jell, this would be the size of an pile of charged jell that had the ...
WebThe size of a photon is equal to the Planck's length, ~10-35 m; though the photon cross section can be spread till 10-32 m --- because when the photon hops from cell to cell in the teasel-lattice ... WebDec 24, 2006 · 0. Point particles have a nasty habit of having infinite energy densities , but it is true that QM assumes particles to be point like. Super String Theory assumes all particles to be small strings with a length of just about the Planck length and no width, i.e. one dimensional . In that case a photon is 10e-44 meters.
WebApr 30, 2024 · The pupils of the eye might have a 2mm diameter in bright light, so receive around $6.2\times 10^{-9}$ W. Let's assume that the average blue sky photon is at 400 nm with an energy of 3.1 eV, then you receive about $10^{10}$ per second (in each eye). WebSep 12, 2024 · The effect is most noticeable when the aperture is small, but the effect is there for large apertures as well. Figure 4.6. 1: (a) Monochromatic light passed through a small circular aperture produces this diffraction pattern. (b) Two point-light sources that are close to one another produce overlapping images because of diffraction.
