Absorbtion Data for Spinach Extract
Laura and Megan carried out the procedure to gather data for an
absorbtion spectrum of a crude spinach extract. The data was collected
as % transmittance (relative to the solvent control). The first step is
to convert this "% transmittance" to "% absorbtion" by
subtracting the transmittance from 100. Record this in the table. Plot
this data on some graph paper. (you can find free graph paper online -
use google and search for "free graph paper".)
x-axis (the independent variable) should be wavelength in nanometers.
y-axis (the dependent variable) should be % absorbtion.
<the data for this part was given in lab on Wednesday but it will be posted here this weekend>
As I get data from the second part of the lab, I will post some here for your view and comparison.
