What is a photon vs electron?

Photon is a type of elementary particle which acts as a carrier of energy, but the electron is a subatomic particle which occurs in all the atoms. The key difference between photon and electron is that the photon is a packet of energy while the electron is a mass.

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.

Are electrons made up of photons?

A: No. Photons have no electrical charge, so you can't make a charged particle out of them. They also have integer spin, so you can't make half-integer spin particles (like electrons) out of them.

How does a photon become an electron?

A photon can spontaneously degenerate into a particle with mass and its antiparticle in a process known as pair production. In this process, the energy of the photon is completely transformed into the mass of the two particles. For example, a photon can turn into an electron and an anti-electron.

What creates a photon?

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.

Atoms, Electrons, Photons, and Light

What is inside a photon?

In physics, a photon is a bundle of electromagnetic energy. It is the basic unit that makes up all light. The photon is sometimes referred to as a "quantum" of electromagnetic energy. Photons are not thought to be made up of smaller particles.

Are humans made of photons?

All living organisms emit a constant current of photons as a mean to direct instantaneous nonlocal signals from one part of the body to another and to the outside world.

Are photons created from nothing?

After rotating the SQUID at those high speeds, the team were able to detect several real photons that were essentially created from nothing. These were the virtual transformed to the real. The photons that were created weren't actually visible to humans - they were in the microwave range of the EM spectrum.

Is an atom a photon?

Photons are very special particles. Elementary particles like electrons, protons, neutrons or composite quasi-particles like atoms, molecules, ball-bearings, planets, stars, etc. share one important feature; they have mass. Rest mass.

Is a photon a real particle?

Physical properties. A photon is massless, has no electric charge, and is a stable particle.

Do photons carry energy?

Since photons (particles of light) have no mass, they must obey E = pc and therefore get all of their energy from their momentum.

Is a photon a particle?

Considered among the subatomic particles, photons are bosons, having no electric charge or rest mass and one unit of spin; they are field particles that are thought to be the carriers of the electromagnetic field.

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.

Is a photon bigger than an atom?

If photons are smaller than atoms, why don't they pass through solid matter? : r/askscience.

Where do photons go when you turn off the light?

The light originated from the tranisition between energy levels, and it bounces around and eventually reaches your eye. When you turn the light off there are no more photons being emitted, and instead they will be scattered and absorbed by items in the room.

Are black holes made of atoms?

The bottom line is that black hole atoms are dark, massive, non-interacting particles. “These properties are just one needs for the dark matter candidates,” say Dokuchaev and Eroshenko.

What the heck is a photon?

A photon is a purely quantum mechanical object representing the smallest piece of energy (or quanta) for light.

Do we have gold in our body?

Average human body has 0.2 milligrams of Gold.

Human body has Gold! A human body is composed of many elements. One of the lesser know elements is actually Gold. An average person's body weighing 70 kilograms would contain a total mass of 0.2 milligrams of gold.

What is human energy called?

Human power is work or energy that is produced from the human body. It can also refer to the power (rate of work per time) of a human. Power comes primarily from muscles, but body heat is also used to do work like warming shelters, food, or other humans.

Does human skin glow in the dark?

The human body literally glows, emitting a visible light in extremely small quantities at levels that rise and fall with the day, scientists reveal.

Do photons live forever?

But if they do have a little mass, they could eventually decay into lighter particles. Now, by studying ancient light radiated shortly after the big bang, a physicist has calculated the minimum lifetime of photons, showing that they must live for at least one billion billion years, if not forever.

Is a photon just light?

A photon is the smallest discrete amount or quantum of electromagnetic radiation. It is the basic unit of all light. Photons are always in motion and, in a vacuum, travel at a constant speed to all observers of 2.998 x 10⁸ m/s. This is commonly referred to as the speed of light, denoted by the letter c.

Can light go on forever?

Nope! Light is a self-perpetuating electromagnetic wave; the strength of the wave can get weaker with the distance it travels, but as long as nothing absorbs it, it will keep on propagating forever.

Do electrons absorb photons?

From a physical particle perspective, an electron (free or bound to an atom) cannot and does not absorb a photon. The atom absorbs the photon and takes its kinetic energy.
