So absorbance right here.

If transmittance is a low number, that means you're absorbing a lot.

So let me do that in a different color.

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

Black cloth absorbs light.

Black paper absorbs light.

So let me write down M for molar.

Modulus

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

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

The x ray absorption spectroscopist's periodic table

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

let's say 0.2 molar.

And that's true of any sample statistic.

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

So if transmittance is a large number, absorbance is a small number, which makes sense.

Photon numbers

Count

Correlation

Extinction

Cooling factor

It cannot hide behind the black hole.

You might have heard that light is a kind of wave and that the color of an object is related to the frequency of light waves it reflects.

So I can just rewrite that as A so now A is not a function anymore, it's just a number A times the second derivative of y, with respect to x, plus B times the first derivative, plus C times y.

If you're good at transmitting, that means you're bad at absorbing, you don't have a lot to absorb.

And over here you're measuring absorbance, in the vertical axis you measure absorbance.

If you're transmitting a lot of light, the absorbance number's going to be very small, which means you are not absorbing that much.

The Beer Lambert law tells us that the absorbance is proportional

You could then measure for some unknown concentration.

Scale by factor

Next I want to focus for a little while on the notion of a clustering coefficient.

This is supposed to be a constant

Max. number of light sources

A higher number says your transmitting a lot.

So there's a fair amount of interconnection between a node's neighbors.

So just getting it correct to a couple of digits is probably sufficient.

2nd derivative r squared.

My eyes were intent on the scene.

So you measure its absorbance and you get its absorbance.

Or another way to say it is that the absorbance is equal to some constant it's usually a lowercase epsilon like that and this is dependent on the solution, or the solute in question, what we actually have in here, and the temperature, and the pressure, and all of that.

Now it's about eighteen.

We are honored by your friendship.
