General Knowledge quiz II

[Krill]

Forum needs that upgrade bad...

Sorry, I suppose you don;t get many chemists on this forum then?

I'm sure even most chemists would say that it was reflecting the colour of the sky! I did physics at uni and that's what I answered first, before being asked the obvious question: "What about when it's cloudy?" It's one of those things you're taught when you're a kid that just sticks.

 

[Krill]

Well whenever I see the sea it's grey, so I'd say it's reflecting the colour of the sky pretty well...

 

[jeps]

can't think of anything good, open floor.

 

[choxorn]

It's usually greyish when it's cloudy, so it at least reflects the sky somewhat.

 

[BananaLee]

Well, why is the SKY blue?

 

[Perfection]

Selective atmospheric absorption of nonblue.

 

[BananaLee]

Not exactly. That wouldn't explain red sunsets.

 

[Perfection]

Your question presumes a blue sky.

 

[Diamondeye]

... That kind of argument calls for an open floor - please?

 

[BananaLee]

*sigh*

It's selective *scattering* of blue wavelengths of light by air particles.
The reason why skies are red in the sunrise and sunset is because light has to travel further through the atmosphere - by time which most of the blue wavelengths have been scattered about while the other wavelengths were transmitted to the point experiencing dawn or dusk.

No absorption occurs

 

[Mise]

Maybe the next question should be "what colour is the sky?"

 

[BananaLee]

*muttermutter* Philistines

 

[Marsden]

You mean the sky isn't blue because it reflects the color of the ocean?

 

[Diamondeye]

:suicide: Can we move on please

 

[nonconformist]

I'd like to argue this in terms of electron density, so you're all wrong

 

[Sofista]

Who's buried in Grant's tomb?

 

[choxorn]

Ulysseus S. Grant and his wife.

 

[Sofista]

Yeah! Choxorn wins!

Where were Venetian Blinds invented?
