Speaker 1 (00:01):
Fact of the day, day day, day.

Speaker 2 (00:04):
Day didn't do doo.

Speaker 1 (00:14):
Del Guys, what's the last day of cloud It's the
last day in cloud week.

Speaker 3 (00:22):
It's it's been a good week.

Speaker 1 (00:24):
Today. Is a simple but rad fact about clouds. That's white.
They're white.

Speaker 3 (00:29):
Oh my god.

Speaker 1 (00:29):
I literally made a joke saying clouds of light was there.
First of all, we need to address white. The sky
is blue because the sun produces white light. So why
is the sky blue because the ocean's blue?

Speaker 3 (00:43):
Wasn't that always.

Speaker 1 (00:44):
Reflecting in the ocean.

Speaker 2 (00:45):
The sky is blue because the ocean is blue, and
the ocean is.

Speaker 1 (00:49):
Because of the light. The ocean, I believe, is blue
for the same reason. The sky is blue, but it's
not reflecting the ocean. It's blue white white light. I
said that the sun. It's out there millions of miles away. Yeah,
like a huge gigantic nuclear furnace hydrogen and Haley, you
could walk. Bring it on, iron man, it's putting out.

(01:13):
We get the heat too. We trap the other of
the heat. But the light comes screaming towards us as
white light. It hits our atmosphere, and violet and blue
light have the shortest wavelengths so when the sun, like
the day, the sun has the shortest way to come
through our atmosphere. It has taken the shortest way, thus
the shortest wave length. Right, and you know on a

(01:37):
really nice day, when the sky's up the sun and
the sun's directly above you, the sky almost does look violet.

Speaker 3 (01:45):
Mm hmmm.

Speaker 1 (01:46):
It's because that's another one of the short waves. Yeah, yeah,
it's different. There's that blue and then there's that real
intense blue. Well when that same light comes through and
hits the clouds which are water mill kills, Yeah, it
takes it back to white light because it's going back
to the it reflects. It reflects it at all wavelengths again,

(02:11):
which is why it's white light. It's it's the little
water droplets.

Speaker 2 (02:16):
Can I just note to the listener that can't it
can't visually see us has not referred to as notes once.
He has actually wrapped the skin around this understanding because
and put it into Layman's terms for us, even as
a qualified doctor. You have Layman's terms this and I
really appreciate it.

Speaker 1 (02:37):
And that's why, like dusk, it goes red because the
the white light has to go further throw at hear
it like, like, how do I describe this? If you're
cutting a cake, for example, and you're cutting straight to
the center in a straight line, chocolic character, it does

(02:58):
with lemon I sack no cream cheese. The shortest way
through is blue. But then if you were to cut
across the top, it would be a longer way through.
But then my cake turn blue.

Speaker 3 (03:10):
Huh is it a boy or a girl?

Speaker 1 (03:11):
It's a girl, oake. Okay, so it turns red, right, Okay,
So that's why you lost.

Speaker 3 (03:17):
Me on that way. T I've understood the.

Speaker 1 (03:19):
Blood stupid analogy. It was just sort of we're in
the middle and it's going like that. I don't need
to understand, don't.

Speaker 3 (03:26):
Yeah, Like I've tuned out because.

Speaker 1 (03:27):
It's got lights.

Speaker 3 (03:29):
Got the first one and that's enough.

Speaker 1 (03:30):
The light is longer, catches the longer wave legs.

Speaker 2 (03:36):
Let my brain diges the first bit of information a.

Speaker 3 (03:39):
Bit too much on the little bit too much, doctor, Yeah,
rightect The clouds are white because the white light that
has turned blue by our atmosphere turns white again when
the water droplets reflect all of the lights.

Speaker 1 (03:55):
And there's a cake somewhere in there.

Speaker 3 (03:56):
As well, somewhere banana cake.

Speaker 2 (04:00):
Fact of the day, day day day day.

Speaker 3 (04:05):
Do do do do do do do do do do do.

Speaker 2 (04:08):
Do do do do do do do do do.

Speaker 3 (04:10):
Do do do do do do do.

Speaker 1 (04:15):
Someone asks why storm clods are black. It's because the
light gets absorbed. There's too much I can consider that
can't get out.

Speaker 2 (04:20):
Told them to don't anymore.

Speaker 1 (04:24):
You guys are the cake, the cake cake whelmed
