Answer: The wavelength of a 2 eV photon is given by: l = h c / E ph = 6.625 x 10-34 x 3 x 10 8 /(1.6 x 10-19 x 2) = 621 nm. An electron is generally considered to be larger than a photon, because nobody has yet been able to measure the size of a photon (to my knowledge). Elementary Electronic Questions; photon vs electron speed + Post New Thread. Electron: Build cross platform desktop apps with web technologies. I want to create an algorithm that users who watch others videos earn points (randomly but in clear context) If you have anything else to improve, please let me know. With Electron, creating a desktop application for your company or idea is easy. The speed of light is around 300 000 000 m/s (it is just less). I had the same question.
8.02x - Lect 16 - Electromagnetic Induction, Faraday's Law, Lenz Law, SUPER DEMO - Duration: 51:24. A photon is charge less particle. Photons travel at the vacuum speed of light (more commonly just called the speed of light) of c = 2.998 x 10 8 m/s. Because of the mass-energy relationship E=mc 2, you can attribute the mass E/c 2 to the photon, and now it is much less than the mass of the electron. Momentum of the photon with frequency ν is: P=hν/c. It just scatters ala Compton. 1,761,942 views can you advice me which equations do I need to use for this question? Atoms are the building blocks of all existing substances. Lectures by Walter Lewin. Node.js or Laravel ( PHP) I need a good performance with high speed, and the most important thing is the ability to handle user's requests if the site's traffic increases. The speed of a photon is different than the speed of electricity. Physically, photon is a massless energy package that according to relativity theory would have the highest speed in a given medium (no matter what the medium is) with respect to any particle that has a defined mass (Ex. The key difference between proton and electron is that proton is a subatomic particle found in a nucleus of an atom, whereas electrons are particles orbiting the nucleus.. Because electrons carry a net charge, the value of which is 1.6 × 10-19 coulombs (C), they are accelerated in an electromagnetic field in a manner analogous to the way ordinary particles are accelerated by a gravitational field or other external force.
The question as asked is vague. Orange light with a wave length of 620 nanometers is composed of photons with energy of 2 eV. Results 1 to 8 of 8 photon vs electron speed. Quantum teleportation is a process in which quantum information (e.g. The electron also seems to “max out” at a speed that is way too slow even if I manually increase the speed value. Why is the speed of an electron greater than that of a proton? A particular electron exists at a specific position in space, travelling in a certain direction at a certain speed*. Also calculate the wavelength of a free electron with a kinetic energy of 2 eV. If Less Movement is possible then Shorter Wavelengths would be assigned. the exact state of an atom or photon) can be transmitted (exactly, in principle) from one location to another, with the help of classical communication and previously shared quantum entanglement between the sending and receiving location. Also calculate the wavelength of a free electron with a kinetic energy of 2 eV. Answer: The wavelength of a 2 eV photon is given by: l = h c / E ph = 6.625 x 10-34 x 3 x 10 8 /(1.6 x 10-19 x 2) = 621 nm. The value of Planck's constant, h, is 4.136x10-15 eV-sec and the velocity of light, c, is 3x10 8 m/sec or 3x10 17 nm/sec so that hc=12.4x10 2 or 1240 eV-nm.. Where is the speed of the electron more compared to that of a proton.
