Question

If we let a pulse of light to spread through space ,what will happened to it finally...???

Answer 1

Photons continue in what they consider to be a straight line, forever, until they're absorbed by some object.  

Answer 2

Well I guess when it hits an object... that object will absorb the light for whatever duration of time the light was initially flashed into space. That makes since, doesn't it?

If it never hits anything... the light will keep traveling through space.

Answer 3

NASA's Cosmicopia -- Ask Us - Space Physics - Energy Traveling ...

He said on "....if a pulse of light is emitted at a particular time at a particular point in space, then as time goes on it will spread out as a sphere of ...

Answer 4

Nothing!

The ligth will keep going on and "spreading through space"... till the battery that supplies it lasts!

ihihihihihihihhahahahahhahah..

Answer 5

It'll go on forever, as far as we know, unless something acts on it or it acts on something else.

However, the chances of it being distinguishable from the background radiation in the universe are slim.

Answer 6

It just keeps going, untill or unless it is affected by something in it's path. It can be reflected by a planet and space dust, it can be bent by gravity, absorbed by a star or black hole.

Answer 7

light can be absorbed, transmitted, and reflected. when particles in the air are stuck by light, the ray of light can be reflected off he particle or absorbed by it. transparent substances such as glass and some plastic can transmitt light by letting the ray pass through it. water transmitts light, but also refracts it. the reason some rays of light (like flash lights) cannot penetrate the earth's atmosphere is because the particles of gase, dust and water vapor absorb it. if the light is reflected, the specturm of light will continue being reflected until it is absorbed or it goes on into a spectrum undetectable by the hman eye.

Answer 8

The photons will encounter a solid object, and collide with it. The energy will be converted into heat, and the light will dissipate.

Answer 9

I am guessing it would keep on going unless something got in it's way to stop it! I am not sure if the radiation in space would gradually deplete the light wave.
