Will light pass through the vacuum?

Answer 1

Yes! If it couldn't, we would not be able to see the Sun, or any other star. For that matter, life on Earth would not exist if it didn't travel through a vacuum.

A very interesting aspect of the question: This question led many serious scientists to speculate that there must be an as yet undetected "ether", or substance, filling every bit of space, and it is through this "ether" that light waves move. Some very famous experiments by Michaelson and Morley determined the answer.

Light is the visible spectrum of electromagnetic energy, and it has some properties that are like "waves", thus the question about vacuums, and some properties suggesting light is a "particle". I guess the answer is that it is both, and neither. electromagnetic radiation is its own amazing thing.

Answer 2

Yes, light travels in a vacuum, and that is what we use as the constant, 3x108ms-1

but sound can't, because sound produces waves and pushes the particles in the air. If there are no particles in the air like in a vacuum, then no sound can travel through.
Yes light can travel through vacuum. It s because light waves consists of magnetic field which is perpendicular to electric field which results in creation of potential difference between two points and light wave propagates.

In this way light doesn't needs any medium to propagate.
I'm not a scientist, but yes it can travel through a vacuum.

==========================================

Even if you were a scientist, it would do that for you.

With our eyes, here on Earth, we see the sun, the moon, and the stars. The way

that happens is: The light from each of them crosses vast distances on its way to

our eyes, through space, which is vacuum.

Answer 3

Yes. Refer to stars - space is a vaccuum (though not a perfect vaccuum) and because light can travel through a vaccuum, we have day and night here on Earth. We can even see light from other stars light years away.

Answer 4

Light does travel in a vacuum. It doesn't really need a medium in order to be transferred from one place to another. Space is actually a vacuum, and the only way that the sun's energy can travel to us is in the form of light, because vacuums cannot conduct heat! Light actually travels the fastest in a vacuum as there is nothing to slow it down. This is the true speed of light, and it actually travelles slower in things such as air and water. The denser the medium, the slower it travels. Hence the refraction observed when light is travelling from a lighter medium to a denser one.

Answer 5

No, light cannot pass through a vacuum because there are no particles or medium for it to travel through. Light travels through space in the form of electromagnetic waves, which do not require a medium to propagate.

Answer 6

Of course, otherwise we would receive no light from the sun

Answer 7

Yes. Light travels best in a vacuum, where there is no matter to interfere with its movement by absorption, reflection, or refraction.

Answer 8

yes

the space between sun and earth is a vacuum

Answer 9

Yes it does.
