Sound is the vibration of molecules and atoms. Light is made up of things called "light quanta" or "photons." This means that sound cannot travel through a vacuum (there are obviously no molecules or atoms in a vacuum to transmit sound) but light can.
Light does travel through a vacuum.
Light is said to be transmitting when it is passing through any matter i.e. not through a vacuum but through a gas, liquid or solid. Light waves move at their highest speed when passing through a vacuum and slow down when passing through matter due to their interaction with the electrons around atoms, molecules or crystal lattices. Optical fibres made of special types of glass are used to transmit light signals in a similar way to copper wires used to transmit electrical signals.
No.
Light can travel through vacuum, but it is not a medium.
You create a vacuum in a lab, and then shine a light through it, and there is experimental proof that light travels through a vacuum. Alternatively, take the fact that light travels through space - if light could not travel through a vacuum, no light from the stars, the moon or the sun would ever reach our planet.
In a vacuum. Light can travel through outer space (Moon to Earth), but sound cannot because sound requires air to transmit the vibrations that we recognize as sounds.
it travels at c (speed of light in a vacuum)
No, light is at its fastest in a vacuum.
Sound waves cannot propagate in a vacuum. Sound waves travel through matter, and a vacuum is, by definition, the absence of matter.
No. Only light waves can travel through a vacuum.
They all travel through a vacuum at the same speed - The speed of light.
Light travels fastest through vacuum.
No. Sound depends on a medium (air, liquid, or solid) in order to transmit. A vacuum, by definition, has no molecules to do the work.
Light acts as a particle.
When the light is traveling through vacuum.
Mechanical waves can't pass through a vacuum. Mechanical waves need something to pass through. Space is generally considered a vacuum, with nothing in it to transmit a mechanical wave.
A vacuum.
Did you ever see light from the Sun? Light is an electromagnetic wave, and it travels through a vacuum to reach us.
Sound will propagate through any matter, but not a vacuum, light will propagate through a vacuum, but only through transparent matter.
Transparent materials fully transmit light, translucent materials partially transmit light and opaque materials do NOT transmit light.
Light can. Sound can't.
TRANSPARENT :) it means see through
if it is translucent, yes if it is opaque, no
Yes. Matter may also transmit light through it.
