Why it's said that light particles does not have mass.As we know that every energy emitting particle every matter has mass though light particles emits both heat and light energy unlimitlessly.So obviously it should have some mass?
1 Answer
Photons, which are light particles, have energy and zero mass, but they do not emit either heat or light.
Explanation:
Photons are the particles which light is composed of. They travel at the speed of light which means that they must have zero mass. Any particle with mass can't travel at the speed of light as it would require infinite energy.
Energy takes many different forms. All interactions must conserve energy. Moving objects have kinetic energy. Heat is actually the vibration of atoms and molecules.
Hot objects cool down by emitting infrared radiation which is a form of light. They may also emit visible light. Light is made up of photons which have energy. How objects cool down by emitting photons which reduce their energy.
Photons are packets of light which each have a very distinct amount of energy. The energy is directly proportional to the frequency of the light.
Photons don't emit light. They are light. As photons travel at the speed of light they also do not experience time. They can only do three things. They can be emitted by matter which needs to lose energy. They can travel at the speed of light. Finally they can be absorbed by matter which gains energy as a result.
