just been informed??? mmmmmm?

Question

been informed that light gaps in between photons reflects of dust particals therefore filling the spaces so therefroe the beam is then intact as a beam!!!! and not a series of seperate photons with spaces , but wot if a space is not filled with a dust particle but is empty as in say a vacum , it this space then in total darkness and what then happens to these spaces in my first question come on guys i need convincing here also but dosent light only reflect of something when it hits it and not until ?

Answer 1

i think you all need to remember that this question only came about because of the first two questions and the first is the one that needs answered..and to add the light only illuminates the ground below the shade as it reflects of everything else , walls ceilings that it reaches and reflects it at angles all around it hence illuminating places it has no direct access too so einstine is not completely right if you have a black pipe in a dark room and you shine a light up it, it will not illuminate to the sides as it ecapes the end of the pipe but only infront unless it hits a wall i have a major theory on the universe if anyone wants to ponder over it...email my boyfriend at [e-mail]

Answer 2

There is no light to see unless photons enter the eye. Photons, yes; light, no, where light, by definition, is visible.

The only way photons can enter the eye and be visible is to be looking directly at the source of the photons or indirectly via reflected light from that source. That's why deep space is so black; there's very little there to reflect the photons into your eyes.

Recall those adventure movies where the hero wants to rob a museum of a priceless painting? What does he do first before he in sneaks into the tight security of the room where the painting is kept. (No after putting up the false video security picture.)

Right, he spritzes the secure room with mist so he can see the laser beams that would trip the alarm. Those laser beams are invisible (presuming a pristine air) until the mist reflects them into our hero's (and our) eyes.

Answer 3

You do not see a beam of light in clear air , the reason you see a beam is because the photons are striking particals of matter in the air or vacuum. A far distant object which cannot be seen with the naked eye or a camera taking a`snapshot` would require the camera to operate in time exposure mode which would allow the photons of light to build up to become an image.

Answer 4

dust particles between photons???? ridiculous. First of all, the size of a photon is so much smaller than a dust particle it is like a grain of sand between 2 objects the size of planets. I'm not exactly sure what your asking as far as light in space in the 2nd part of your question.
Light is in fact a beam because of the sheer number of photons traveling in this ray of light. They hit an object and are reflected. The only way you see a beam of light is yes that they are reflected by dust, bu that in no way contributes to the beam itself.

Answer 5

Looking back at your previous questions you seem to be examining the possibility of certain phenomena apparently contradicting the limit of the speed of light.

I think you should remember that Einstein's statement that nothing can travel faster than the speed of light only applies to objects with a rest mass greater than zero.

This wave/particle duality aspect also seems to be generating a fair amount of comment. Light can behave as either a wave or a partilcle, depending on the measurements being taken.

Answer 6

There are gaps but you'd have to travell at light speed to see them.

If a stream of photons passes in front of your eyes you couldn't see the gaps between the photons as they are also passing you at light speed.

You'd need some seriously good equipment (not yet available) to be able to film the photons and then slow them down enough to be able to see the effect

Answer 7

sorry, i`m not einstein but i read this dust thing in a book (intro to einstein) a ceiling light wiv uplighter shade will still iluminate the floor below the shade which i think indicates that all the atmosphere has just so much small particles of dust, but use the same light and shade in space (vacuum) and anything below the shade will not iluminate.
God, your questions are hard work

Answer 8

Light is both a particle and a wave. Concept is called "duality"

Answer 9

i can't understand you when you don't use any punctuation and your entire question is a runon sentence with 2 questions in it.

i think the answers are the spaces stay dark
and yes

Answer 10

yes
