In particle physics, heavy particles typically refer to those with a large mass, such as protons, neutrons, and certain heavier quarks like top quarks. Light particles include electrons, neutrinos, and lighter quarks like up and down quarks. The mass of these particles influences their interactions and roles in fundamental forces and atomic structure. Generally, heavy particles have a more significant gravitational influence and contribute more to the mass of atomic nuclei.
In optics, the transfer of light energy to particles of matter is called absorption. This occurs when the photons of light are absorbed by the particles, resulting in an increase in the particles' energy level.
inertia: the tendency of an object to resist a change in its motion If a light rock is being thrown at a heavy rock the light rock would probably crack or get deflected from the heavy rock, but if a heavy rock is being thrown at a light rock the light rock would most likely shatter. A: The heavy rock has more inertia
Massless particles traveling at the speed of light include photons, the particles of light. They have no rest mass and always move at the speed of light in a vacuum according to the theory of special relativity.
The particles of light are called photons.
High-frequency light, such as ultraviolet or gamma rays, interacts more strongly with small particles compared to large particles. This is due to the wave-particle duality of light and the fact that smaller particles, like atoms and molecules, have dimensions comparable to the wavelength of high-frequency light, allowing for significant interaction. In contrast, larger particles tend to scatter or reflect light rather than interact with it at the quantum level. Therefore, small particles are more affected by high-frequency light.
Density is the measure of how light or heavy something is for its size, calculated by dividing the mass of an object by its volume. It indicates how compact the particles are within a substance.
Particles that are heavy. Mass is like MASSive (massive) and massive objects could be heavy.
Light particles are called Photons.
... particles.... particles.... particles.... particles.
Another word for "light" as in not heavy is "lightweight."
The opposite of heavy is light.
proton
In general lighter particles should diffuse faster than heavier particles, this could be extrapolated from the relationship to mass, volume, and energy. If we look at particles of all the same, ideal, substance, we would see that an object with less mass would be smaller but would also require less energy to move. That is, at the same temperature a particle of lower mass would move faster than a similar particle of heavier mass. We also see that smaller particles also maximize surface area/mass - this is also conducive to faster diffusion.
Light particles are called Photons.
photon
The particles of light are known as photons.
When light is emitted as particles, it is called photons. Photons are the basic unit of light and have properties of both particles and waves.
