What wave can travel through space where there is no matter?

A light wave can travel through space. Otherwise, how would sunlight reach the Earth? Also, light does have wave-like structures, and it is made up of particles called photons.


Why do you get photons or other particles in annihilation of subatomic particles?

In annihilation between electron and positron, you should get nothing in your hand. Instead of that you get a pair of photons. The question is that why should you get the pair of photons. So this is not complete annihilation. The answer is simple to this question. When you bring the electron and positron slowly to each other, they will annihilate to each other and will not produce the photons also. But when the particles come with high speed, they carry the energy and have momentum. This energy is converted into photons of different wave length and the electron and positron disappear or get completely annihilated. When you have heavy particles like protons and anti-protons or neutrons and anti-neutrons strike to each other, you get much larger amount of energy that is left. Because they are brought to each other at high speed, they have high momentum and so carry the large amount of energy. This energy is liberated after the annihilation. When enough quantum of energy is there, you have production of electrons, positrons and neutrinos get generated. The rest of the energy is left in the form of photons. When larger molecules of matter and antimatter will collide with each other, you may get smaller molecules of matter and antimatter in your hand.


What is changed when matter undergoes a phisical change?

When matter undergoes a physical change (like changes in the state of matter), the space between the particles in the matter and how the particles move change.


What are the particles of light energy called?

All electromagnetic radiation, including light, radio, X-rays etc. has particle-like behavior.The particles have been given the name "photons".


Is light only made out of photons or even just waves and how can we see waves in a form of light?

Light can be understood as both particles (photons) and waves. According to the wave-particle duality concept in quantum mechanics, light exhibits properties of both particles and waves. We cannot directly see light waves, but we can observe their effects, such as the illumination of objects or interference patterns, which can be detected by our eyes or scientific instruments.

Well, they're probably not really particles ... but they're called "photons".

no...but there are particles which have speeds closer to light,like photons,god particle(matter-wave)particle


Can Matter be transported at speed of light?

It depends on how you look at matter. For example, photons are what is known as the particles of light, so imagine light being a stream of particles. These will travel at the speed of light within a vacuum. As of yet we have not achieved, and are nowhere near getting large matter like a person to travel anywhere near that speed.


What is between particles of gas?

Its mostly just space. There might be some things like photons in between them.

How can particles be without mass?

All particles that move slower than the speed of light have a "rest mass" or "invariant mass" - and that means, almost all particles. One of the few particles that does NOT have a rest mass is the photon, since it moves at the speed of light. It does have energy, and therefore (by mass-energy equivalence) it also has mass, but this is not "rest mass" and is often not counted as mass.

Why any object cannot travell with the speed of light?

Some particles, like photons and gravitons, are believed to ALWAYS travel at the speed of light. Particles, or larger amounts of matter, that move at a slower speed can't be made to travel at the speed of light - according to the Special Theory of Relativity, that would require an infinite energy.
