Why is it light with white curtains?

[Coyote]

With the development of quantum mechanics in the 20th century came the decision that it's both! Light can act like a particle and a wave and the same time. We just see different aspects of its nature at different times. If this at all seems strange, don't worry. Quantum physics is confusing to most people, even to the people who invented it!

Technically, it isn't both. It just has properties of both, but isn't one or the other. So that funny haired dude decided that they were little packets of energy, aka photons.

Pity I didn't get university entrance so I could study quantum physics further.

So why does all the sunlight come through white curtains while black curtains leave the room nice and dark?

The white curtain will reflect ALL available light, whereas the black curtain won't. So with the white curtain you get reflected and transmitted light and the black curtain only gives transmitted light.

Also while the white is reflecting the light some of that light is being reflected in throught the stitching etc... giving more visual light inside, while the same light on the black may be absorbed giving a darker appearance.

to fix this problem you first must apply the soultion.

Try reversing the flux capasitor's polarity, it worked for me, only after i checked the tyre pressures tho!

What am i, a light bulb????

[paturoa]

So what to you particle and wave pundits have to say about diffraction grates?

I Like the multiverse theory where Hondas aren't ghey and white curtains let in white light.

[homer]

so hows this work then

ok
so white reflects all available light ok
and black reflects less light ok

so how come i dont see my head light in the day time on the road which is a dark colour ..."because it reflects not a lot of light "?

or

How come at night on the back roads when theres no light i see everything with my head light on

and if its all dark at night then i should see anything except the road markers or signs which of course reflect.

[Skyryder]

At school i was taught that white reflected all the coloured light. It was the "all" colour.

Black on the other hand didnt reflect nuttin'. Nuttin' at all.

So why does all the sunlight come through white curtains while black curtains leave the room nice and dark???????

If i could be arsed i'd open a new browser tab and go to google. but i cant so enlighten me (bahahahahaha)

Yes I picked the wrong day to give up sniffing glue.......

It's not about reflection but absorption. The white curtains do not absorb the light so the room stays light the black curtains absorb the the light and so the room is darker.

This i also know myself your quite correct
but explain my post in this thread

[Finn]

More worryingly, is light a particle or a wave?

Not another fucking waving thread!

[homer]

light cant be "unless your in space on the edge of a black hole " waves .
light dosnt bend unless the stated above happens
its definately in lines
but they do spread so a torch beam gets wider
as a lazer does get wider as well but not the same amount

[Wheels of Fire - In the Studio:]
In the white room with black curtains near the station.
Black-roof country, no gold pavements, tired starlings.
Silver horses run down moonbeams in your dark eyes.
Dawn-light smiles on you leaving, my contentment.
I'll wait in this place where the sun never shines;
Wait in this place where the shadows run from themselves.
You said no strings could secure you at the station.
Platform ticket, restless diesels, goodbye windows.
I walked into such a sad time at the station.
As I walked out, felt my own need just beginning.
I'll wait in the queue when the trains come back;
Lie with you where the shadows run from themselves.
At the party she was kindness in the hard crowd.
Consolation for the old wound now forgotten.
Yellow tigers crouched in jungles in her dark eyes.
She's just dressing, goodbye windows, tired starlings.
I'll sleep in this place with the lonely crowd;
Lie in the dark where the shadows run from themselves.

I see a red door and I want it painted black
No colors anymore I want them to turn black
I see the girls walk by dressed in their summer clothes
I have to turn my head until my darkness goes
Hmm, hmm, hmm,...
I wanna see it painted, painted black
Black as night, black as coal
I wanna see the sun blotted out from the sky
I wanna see it painted, painted, painted, painted black

Light rides on a particle wave which makes it visible light and visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together, they make white light.

Light is a form of energy visible to the human eye that is radiated by moving charged particles. There are many unanswered questions about light. Light is very hard to study due to its high speed. One major question about light is the uncertainty of whether light is a wave or whether it is a particle. There is some evidence pointing in both directions but no conclusive proof confirms that it can be classified as either one. Scientists have learned through experimentation that light behaves like a particle at times, and like a wave at other times. Whenever light acts like a particle, we called the particles that make up the light either a photon or quantum. In 1900, Max Planck proposed the existence of a light quantum, a finite packet of energy which is a photon.

Good post - however it is quanta - from which we get quantum mechanics. Max Planck is regarded as the father but I think there was another German who did the seminal work 20 years earlier.

As for light, it is wave/particle duality meaning that light exists both as a particle (photon) and a wave of energy (quanta) at the same time. However you'll only detect one state upon observation. A photon has energy but no mass - go figure.

Somebody said light was a charged particle - I thought photons were uncharged?

Can anyone explain the "absorption"? I know it happens but how? Are black curtains low energy? Sort of a frozen value of the universe of curtains?

Sheesh, no wonder Schroedinger's Cat went off to an alternative universe.

How do you explain the as-predicted apparent shift of distant star when their light gets bent "around" another star in-between?

How do you explain the double-slit interference pattern experiment?

but they do spread so a torch beam gets wider
as a lazer does get wider as well but not the same amount

No, that's just individual rays exiting the laser at not-quite the same angle. There is no individual light ray spreading.
