All right, so we're showing this attempt at drawing a calibration curve for the beer lambert law.
00:06
And first we want to know what's wrong.
00:10
Well, upon first glance, we know that absorbance is equal to some constant like a, b, and then times the concentration.
00:26
And so we're dealing with chemical quantities, which should be positive, and the line.
00:36
Should be fitted so that the y intercept is equal to zero.
00:40
And we see in this graph that we have some negative values, which are irrelevant and shouldn't be there.
00:47
And then the y intercept is one.
00:50
So fitting line to the points as attempted in this particular graph doesn't account for the fact that we want our graph to begin around zero.
01:01
Also, it's missing all of the labels.
01:04
So we don't even know.
01:05
Like, by convention, we know absorbance goes on the y -axis, but there's no indication here that the y -axis is absorbance because there is no axis label and there's no unit...
