Sometimes you do in fact. In IR spectroscopy, the transmittance is commonly plotted instead of absorbance.
However, in most types of spectroscopy, the absorbance is plotted instead. This is due to Beer's Law, which states that the absorbance is directly proportional to the concentration of the sample, the absorptivity of the sample, and the path length (in contrast, the transmittance is exponentially related to those things). Because of the much simpler direct proportionality, absorbance is preferred in many cases.

What reasons can you give for the difference in the percentage of transmittance between the live chlorplats that were incubated in the light and those that were kept in the dark?
The percent transmittance grew to steadily higher numbers as the experiment progressed because the light reaction was able to occur. However, the dark cuvettes had stable levels of transmittance because light is necessary to excite electrons, which, in turn, reduces the DPIP.
In a plot of absorbance vs concentration what does the slope represent?
The slope of a plot of absorbance vs. concentration represents the molar absorptivity (also known as the molar absorptivity coefficient or extinction coefficient) of the compound being measured. It indicates how strongly the compound absorbs light at a specific wavelength, and a higher slope indicates a higher absorbance for a given concentration.
What does the slope of a wavelength vs period graph tell you?
The slope of a wavelength vs period graph represents the speed of the wave. A steeper slope indicates a higher speed, while a gentler slope indicates a slower speed.
What decay process will occur if an isotope lies above the band of stability on a plot of neutrons vs protons?
If an isotope lies above the band of stability on a plot of neutrons vs protons, it will undergo radioactive decay.
What decay process will an isotope undergo if it lies above the band of stability on a plot of neutrons vs protons?
If an isotope lies above the band of stability on a plot of neutrons vs protons, it will undergo beta decay.

What is external calibration and is it the same as the manual calibration of equipment?
Well, external calibration is a method used in analytical chemistry to determine the concentration of an unknown analyte. In essence, you take known concentrations of the analyte and plot it on an absorbance or transmittance graph to get a linear plot. And then you take that linear equation and plug in the absorbance or transmittance value received from the unknown solution and get the concentration. An example of this is if you want to find out the amount of calcium in a vitamin tablet. Dissolve the vitamin tablet and test the solution to get an absorbance value. Then test by the same method various concentrations of a calcium solution, plot this on a graph of absorbance vs. concentration and there yah go.
