Can there be light without matter?
Radio waves, light, and other forms of radiation all have energy, but do not need matter. So yes, you absolutely can have energy without matter, in empty space.
Are lights made of particles?
Light is made of particles called photons, bundles of the electromagnetic field that carry a specific amount of energy. The photon model was one of the first triumphs of quantum physics; later work showed that electrons and other particles of matter also have wave-like properties.
How can light exist without mass?
Since photons (particles of light) have no mass, they must obey E = pc and therefore get all of their energy from their momentum. But an object with zero energy and zero mass is nothing at all. Therefore, if an object with no mass is to physically exist, it can never be at rest. Such is the case with light.
Can there be light without darkness?
Yes, as during day time. But darkness can/is always there without light, as in a, enclosed windowless room at pitch-dark night. This is because LIGHT is the PRESENCE of something . DARKNESS is the ABSENCE of something.
Is everything made out of light?
No, everything is matter. Matter is made of electrons and quarks. Light is made of photons. We can call it as a hypothesis.
Is everything made of light?
Can light exist without a source?
Just don’t use it as a sound basis to ask scientific questions. The scientific answer to your question is: ‘yes, of course light can exist without a source. The stars in the farthest galaxies that we see, mostly no longer exist, but the light is still there.
How does light travel in space where no matter exists?
How does light can travel in space where no matter exists? Even where are no particles to support the wave, and wave energy is that which vibrates the particles and moves one particle in relation to another, if particles come into contact, as in water, for instance, we understand how a wave can propagate.
Is light the only massless object in the universe?
Light is such an object, and the universal speed limit cis named the speed of light in its honor. But light is not the only massless object. Gluons and the hypothetical gravitons are also massless, and therefore travel at speed cin all frames.
Can light carry energy without mass?
Light indeed carries energy and accomplishes this without having any mass. The Einstein equation that you are probably referring to is E= mc2. This equation is actually a special case of the more general equation: E2= p2c2+ m2c4
