Is light an example of matter?
No, light is not an example of matter. It is an example of electromagnetic waves. However, it is considered that light is composed of photons (massless particles) and it is applied to it some theories of matter.
What are the three most common subatomic particles?
These particles are: proton, neutron, electron.
Is matter anything that takes up space and has mass?
True, Matter is anything that takes up space and has mass<3 However, physicists say that some particles of matter are massless, such as photons.
Name three conductors of sound?
Three of the most common substances are air, water and dirt. Just about anything that can have its molecules or particles vibrated will conduct sound.
What are solids called if their particles are arranged in repeated three dimensional patterns?
I have no idea, I was actually looking for the answer. 3 dimensional
What doesn't have mass?
There are three known massless particles. Gauge bosons, gluons, and photons.
What is the mass of a massless particles?
Zero.
What are the subatomic particles with no mass called?
All subatomic particles have mass.
What are the subatomic particles with no mass?
photonsgravitonsBoth are bosons, there are no massless fermions although neutrinos were once believed to be massless.
What are massless particles traveling the speed of light?
photons
Is there any particle smaller than neutrino?
I suppose that gluons are smaller because these particles are massless.
What moves as fast as light?
All electromagnetic radiation or massless particles are capable of moving as fast as light.
Theoretical massless particle?
== == The Higgs Boson is another theoretical particle thought to be responsible for the presence of mass in other particles that have mass. I believe the Higgs Boson is theorized to be itself massless. there are 3 known massless particles: the gauge boson, the photon, and the gluon ( the gluon isn't necessarily categorized as a free particle due to the fact that they are confined to hadrons) neutrinos were also, until recently, were thought to be massless. however, they were discovered to change flavor, which means that they must have mass.
What types of energy and matter does the sun release?
Radiant energy in the electromagnetic spectrum. Matter in the form of charged, uncharged and massless particles
What is a real spell that freezes time?
There are no "real spells" and it is not possible to "freeze time" except in the trivial case of massless particles such as photons.
Why light don't travel at an infinite speed?
Because at infinite speed, it's mass will become zero, which is not possible as it consists of photons which are not massless particles.
Is that true that the more energy of a photon the bigger the mass it possesses?
No, all photons have the same mass. Photons are massless (i.e. zero). All the energy in a photon is in its momentum, but increasing its momentum does not change it speed which is always "the speed of light". All massless particles always move at the speed of light.
