Is light energy a form of matter?

Answer 1

no, matter is not a form of energy a matter must exist in the either one of the three states of matter .

wait a minute that isn't what i was asking i was asking was energy a state of matter and plus your forgetting plasma that makes up almost the entire universe and stars. by the way plasma is an electrically charged gas!!

Answer 2

This question is a little vague... There are multiple uses to the word energy. Light is an electromagnetic wave, which is energy, but not necessarily matter. If you mean kenetic energy, the speed of particles in matter, than yes, it is a physical property of matter, as it affects the state it is in (solid, liquid, gas, plasma).

Answer 3

Yes, energy can be converted into matter and vice versa. Consider the creation of an electron-positron pair in pair production by the passage of a high energy electromagnetic ray (a high energy photon) near an atomic nucleus. This is the conversion of electromagentic energy into matter.

It might also be beneficial to consider the conversion of a positron and an electron entirely into energy in mutual annihilation. This is an example of matter being turned into energy. We've cited just one example of conversion in each direction. Use the links below to begin to understand the processes.

Answer 4

Light energy is made up of a fundamental particle called a photon.

Even though photons:

-slow down in matter

-are affected by gravity

-have momentum

-can exert pressure

-can be expressed by E=mc2

they aren't considered to be matter simply because they have no mass.

That does allow them to do some cool stuff though, like travel at the speed of light and occupy the same space with other photons at the same time.

Answer 5

No, they are not.
