Meaningless because of your say so? I think not.
By saying the blue sky is because of scattering is the same as saying 700 nm is blue.
Quote from: Thebox on 26/09/2017 15:18:49By saying the blue sky is because of scattering is the same as saying 700 nm is blue.In what way?After all, nobody else seems to think so, do they?All the books say it's due to scattering.The measurements of scattering cross section say so to.And the lab scale demos show it.So why is absolutely everything wrong except you?
Rayleigh scattering refers to the scattering of light off of the molecules of the air, and can be extended to scattering from particles up to about a tenth of the wavelength of the light. It is Rayleigh scattering off the molecules of the air which gives us the blue sky.
Somethings I deem wrong
why do you keep saying I am wrong without really discussing?
I say how can that be so?
You say light redirected by air and scattered.
I say air is transparent, thin up top and has no permeability,
Physics science forums have learnt me.
In scattering anything, the anything is spread out?
According to you I shouldn't be able to see objects because there would be a blue ''haze'' anywhere there is air.
Because you was told to remember the scattering and you would pass your education, you can't think past it and automatically stereo-typically accept this as the truth instead of thinking for yourself.
Quote from: Thebox on 27/09/2017 14:04:25Somethings I deem wrongYou are not God.It is not in your power to deem something right or wrong.Quote from: Thebox on 27/09/2017 14:04:25why do you keep saying I am wrong without really discussing?Because that's what the evidence shows- and has done so for over 100 years.Quote from: Thebox on 27/09/2017 14:04:25I say how can that be so? Again, because that's what the evidence says.Quote from: Thebox on 27/09/2017 14:04:25You say light redirected by air and scattered. And again. It's not just me. An experiment with a decent laser pen will prove the point.Quote from: Thebox on 27/09/2017 14:04:25I say air is transparent, thin up top and has no permeability,Look up either the common, or scientific uses of the word permeability, and you will see that you are wrong.Things permeate through air- outside my window the rain is permeating downward through the air and is hitting the window. It stops there because the window is impermeable to rain.The scientific use of the word is more complex, but not at odds with the usual meaning.https://en.wikipedia.org/wiki/Permeability_(electromagnetism)Air has a permeability of about 1.3µH/metre.I realise you won't understand that, but that doesn't mean it isn't true.Quote from: Thebox on 27/09/2017 14:04:25Physics science forums have learnt me. The word is taught; and they clearly have not.Quote from: Thebox on 27/09/2017 14:04:25In scattering anything, the anything is spread out? Yes. specifically the light travelling in a line gets forced to deviate from that line.Quote from: Thebox on 27/09/2017 14:04:25According to you I shouldn't be able to see objects because there would be a blue ''haze'' anywhere there is air. Nonsense.There is a blue haze- and you can sometimes see it- especially if the air is foggy.But the effect is small.So most of the light gets straight through- some small faction- perhaps 1 part in a million- is scattered off to one side on passing through each metre of air.But, as the layer of air you look through gets thicker- for example that air between you, and the sun at the sunset, the effect becomes more obvious.Quote from: Thebox on 27/09/2017 14:04:25Because you was told to remember the scattering and you would pass your education, you can't think past it and automatically stereo-typically accept this as the truth instead of thinking for yourself.No, because I have seen scattered light- because I play with lasers, and because I understand the physics, and because I have done Raman scattering experiments, I know that it is true. Light gets scattered.And you just look stupid when you try to second-guess why I believe things.
Do you understand or can you understand that I do not easily accept things to be true?
Now quite clearly if atoms were not transparent we should see some opaqueness of air . Unfortunately we do not no matter how dense the air is.
Quote from: Thebox on 27/09/2017 20:55:55Now quite clearly if atoms were not transparent we should see some opaqueness of air . Unfortunately we do not no matter how dense the air is. We do- with every sunrise and sunset.But you can't understand it.

NoI don't understand why you don't accept obvious truth that has been demonstrated countless times in a multitude of ways, and in spite of people explaining it to you.Why are you unable to face facts?
The stuff on wiki is what I am questioning the integrity of.
Replying with the original stuff does not answer any new queries on the stuff.
Essentially, you don't believe
You have just said you don't like it, and refuse to accept it.
Quote from: Bored chemist on 28/09/2017 19:25:20 You have just said you don't like it, and refuse to accept it. I have asked several queries on several subjects which all have failed to answer.
Sodium vapour is composed of atoms, and is blue.
If you believed it was true you wouldn't be questioning the integrity of wiki etc.It's not mind reading; it's reading what you posted.
Yet you pretend you haven't been answered.
Quote from: Bored chemist on 28/09/2017 20:48:33Yet you pretend you haven't been answered.And air?
Anyway the air is mainly made from molecules, so it's about 99% irrelevant to the topic.
So quite clearly there simply a paradox .
