- There exist positron which is used in medical area to detect abnormal tissue. Photon Calculations III. Momentum of the photon with frequency ν is: P=hν/c. If "size" means mass or diameter a photon is said to have neither. And the dual nature of light is still a bit of a quandary, as it displays aspects of both wave nature and particle nature (the duality principle leads some folks to label photons as "wavicles")! From the definition of the electron volt, we know 1 eV = 1.60 × 10 −19 J, where 1 J = 1 C ⋅ V. Gathering factors and converting energy to eV yields Electron Calculations IV.

A photon is charge less particle. But if using a smaller tool to measure the electron's size, the answer gets smaller as well. Alternate keys are currently unsupported on the Photon but are used on the Electron as UDP/ECC keys. Properties of Electron.

Although photons are often referred to as particles, they aren’t particles in the traditional sense.

As far as interactions is concerned, if the size of the interacting body is L , then we have two extreme cases: for wavelength of the photon << L then the photon may be treated as a particle.

An electron is a charged particle. The strength of the electron asymmetry is quantified by the electron dipole moment , which is defined as something like charge in the bottom half of the electron charge in the top half of the electron electron size).. It depends essentially on the way you want to measure it. An electron has mass and may be at rest.
An electron cannot move the velocity of light. When I researched this at @Electricity is energy [the real title of the article is "Electricity Is NOT Energy"], I found out that electrons are tiny particles of matter. It is neither a particle nor a wave but both!

Yo Electron vs Hero Electric Photon - Which bike should you buy? Curiously, this most common of atomic parts has only a fuzzy estimate of size. It carries energy, momentum and angular momentum; also frequency.

I had the same question. In this case the electron would would want to align its “head” with an external electric field. 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.. - Electron can have kinetic and also potential energy in a solid metal or semiconductor. The size of a fundamental particle is a tricky idea. 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).


The photon is a conceptual packet of energy, which is very important in quantum mechanics.Electron and photon are two concepts that developed greatly with the development of quantum mechanics. In physics, the proton-to-electron mass ratio, μ or β, is simply the rest mass of the proton (a baryon found in atoms) divided by that of the electron (a lepton found in atoms). If using a slow atom to measure the size of an electron on other atom's outer shell, the answer is "the electron has the size of the atom". - If you think electron as a hard object, then its flow in metal may be difficult to imagine, but remember that electron behaves mostly as a quantum mechanical wave. The difference between the size of an electron and the size of a chromosome is much larger than the difference between the smallest and largest objects you can get a feel for. The key difference between photon and electron is that photon is a packet of energy while the electron is a mass.. An electron is a subatomic particle that plays a vital role in almost everything. II.
