### still don't uderrsatnd what a photon is

what exactly is a photon and if you could see it what would it look like

### Re: still don't uderrsatnd what a photon is

A photon is basically a wavelength of light, and is typically portrayed as a squiggly line coming from the sun in many diagrams that involve a photon.

A photon can also be a representation of a particle of light or other electromagnetic radiation.

A photon is massless and has energy.

### Re: still don't uderrsatnd what a photon is

When you are changing energy levels (n), the difference in energy is given off as a photon when you are moving from a high energy electron to a lower energy level. This represents the principle of conversation of energy.

A photon is a particle that represents a quantum of light or other electromagnetic radiation. It also carries energy proportional to the radiation frequency.

### Re: still don't uderrsatnd what a photon is

A photon is the basic unit of all light and the smallest discrete amount or quantum of electromagnetic radiation. It's the force carrier of the electromagnetic force. Additionally, photons are always in motion.

Are photons comparative to electrons in some sense, and could we think of them similar to atoms in some ways?

a photon is the movement of energy in a wavelike motion which is seen as visible light at some frequencies

### Re: still don't uderrsatnd what a photon is

A photon basically is a small amount of electromagnetic radiation or light which is a source of energy.

### Re: still don't uderrsatnd what a photon is

Since a photon does not have mass, is it better to think of a photon as a concept/idea that can be assigned an amount of energy rather than a specific 'particle' that you can visualize like a proton or an electron? not sure if this makes sense

### Re: still don't uderrsatnd what a photon is

The best way to think of a photon is to think of it as light. It is important to note that a photon does not ever have any mass to it.

Photons don't have mass but they do have energy and momentum, so they are able to move with the speed of light.

I like to think of a photon as a packet of light/energy.

### Re: still don't uderrsatnd what a photon is

A photon is a packet of light that does not have mass but it does have energy and momentum. A photon also has both wavelike and particle characteristics.

its basically a particle representing a quantum of light or other electromagnetic radiation. It carries energy proportional to the radiation frequency but with zero mass

### Re: still don't uderrsatnd what a photon is

Would it be wrong to say that a photon is the smallest quantum of light, like how one water molecule is the smallest quantum of water?

How is it possible that photons have momentum if photons do not have a mass and if momentum equals mass time velocity?

### Re: still don't uderrsatnd what a photon is

Energy = momentum * speed of light for the photons, so momentum of a photon is related to its energy.

### Re: still don't uderrsatnd what a photon is

You just need to manipulate the equations and its easy to see the relationship between photons and momentum especially if you do dimensional analysis.

### Re: still don't uderrsatnd what a photon is

is there a certain constant that comes along with the size of a photon?
