You think probable to dust.
Dust particles
Dust particals, ash .ect
Light is quite complicated as it has wave-particle duality. Sometimes it acts like a particle other times like a wave. But technically no, it is not matter, it is made of energy
no...but there are particles which have speeds closer to light,like photons,god particle(matter-wave)particle
Photons interact with matter as a particle; for example, photons can be absorbed and emitted by electrons.
Heat is definitely not matter. However, the question of whether light is matter has been found throughout history as a problem - independent experiments have proven that light can be both a particle (called a photon), and an electromagnetic wave. This is a basic principle of quantum physics, called particle-wave duality.
Light has matter E= mc2 = hc/r thus m=h/cr.
photoelectric effect
In some circumstances, ultraviolet light may inteact with matter to produce heat, but it does not carry heat. Heat is carried by matter in motion since heat (temperature) is a characteristic of matter.
Yes.
No, their detection requires a collider, they are a subatomic particle and their existence is inferred by their affect on other particle of matter, not by light waves.
