The x ray absorption spectroscopist's periodic table

Black cloth absorbs light.

Black paper absorbs light.

This is actually a picture of the spectrum of the Sun.

Absorption

What I want to do in this video is to talk a little bit about spectrophotometry.

So suppose we have an object over here and the object emits light in all directions.

A higher number says your transmitting a lot.

So absorbance right here.

The un digestive food reaches the Ileo cecal valve and enters the large intestine or colon.

Here is another example of something which is this is a little spectrophotometer.

Some of this light, at certain frequencies, is going to be absorbed by our little molecules inside the beaker.

In theory, you could fully simulate the world around you.

Corporate merger?

These light, if you imagine, photons are just going to bump into more molecules.

Cotton absorbs water.

So let me do that in a different color.

Especially less of those specific frequencies that these molecules in here like to absorb.

Rugs absorb sound.

The large intestine absorbs water.

That's a known consequence of geoengineering, if they did it, which they appear to be.

The Iluminacion del Sol, it drains a vampire's power.

We use far red light, but even that's a problem because it gets absorbed so quickly.

This completes the chemical process of digestion

They are actually red that's what gives blood its color.

This paper has very good absorption.

When a tree's done using its leaves its solar collectors, these amazing molecular photon capturing devices at the end of a season, it doesn't pack them up, take them to the leaf reprocessing center and have them melted down to form new leaves.

So let's say there's some unknown concentration, and you figure out its absorbance is right over here.

So let me write down M for molar.

look. So, a diffuse term is fine.

The point here is that we want to know how much light is coming from each direction.

This cloth absorbs water well.

He absorbed new ideas.

Sound absorbing material is called acoustic material.

So once again, it's going to bump into more molecules and more of it will be absorbed.

These pajamas absorb sweat well.

If we continue like this it'll be an operational crisis.

Generally you want to focus on the frequencies that this is the best at absorbing.

And you measure its absorbance, and you just get some number here.

let's say 0.2 molar.

1871

Well more of those specific frequencies of light are going to be absorbed as the light travels through this beaker.

What's going to happen as the light exits the other side of this beaker right here?

I was also inspired by Walt Whitman, who wanted to absorb America and have it absorb him.

He assimilated what he was taught.
