Electrons can gain energy by interacting with photons. If a photon has an energy at least as big as the work function, the photon energy can be transferred to the electron and the electron will have enough energy to escape from the metal.Aug 6, 1999

Is photon and electron the same?

Light, for example, is an electromagnetic radiation. Photons can be said to be the fundamental particles of light….Difference Between Photon and Electron.

It carries a negative charge.It doesn't carry any charge.

Do photons come from electrons?

A photon is produced whenever an electron in a higher-than-normal orbit falls back to its normal orbit. During the fall from high energy to normal energy, the electron emits a photon — a packet of energy — with very specific characteristics.

Which is faster electron or photon?

A photon in a vacuum always travels faster, as it travels at the speed of light, which electrons, being massive particles, cannot achieve. In a medium, it is possible for electrons to travel faster than photons. For instance, in water, a high energy electron can travel faster than the speed of light in water.

Which is bigger a photon or an electron?

A photon is in shape like a thin stick if its energy is lower than the rest energy of an electron and like a plate if its radius is smaller than the classical radius of an electron. For a photon of hν=13.6 eV, the photon radius is 34.9 pm and is less than the Bohr radius.

How does an electron absorb a photon?

Photon absorption by an atomic electron occurs in the photoelectric effect process, in which the photon loses its entire energy to an atomic electron which is in turn liberated from the atom. This process requires the incident photon to have an energy greater than the binding energy of an orbital electron.

What happens to electrons when light is emitted?

Energy and Electrons When an electron is hit by a photon of light, it absorbs the quanta of energy the photon was carrying and moves to a higher energy state. One way of thinking about this higher energy state is to imagine that the electron is now moving faster, (it has just been "hit" by a rapidly moving photon).

Can a photon be destroyed?

Photons are easily created and destroyed. The movement of electrons is responsible for both the creation and destruction of the photons, and that's the case for a lot of light production and absorption.

What is a photon equal to?

A photon is a particlelike packet of electromagnetic energy. The energy E of a photon is equal to hv = hc/λ, where v is the frequency of the electromagnetic radiation and λ is its wavelength.

Is electricity a photon or electron?

Light is ultimately composed of photons. Photons are also force carriers of the electrical force. When an electric motor is turning it is photons which are turning it.
