2. Using the code “color” and combinations of the CPA concentrations recommended in Table 17.1, perform the simulations of water color characteristics and
analyze:
– the dominant wavelength dependence on a number of the CPA combinations;
– the color purity dependence on the same as above CPA combinations.
Note: The code “color” permits to display the simulation results on the PC screen:
you only need to push simultaneously two buttons “Ctrl+O”.
17.2.4 Requirements to the Report
– Using the text editor “World”, make (draw) a concise report reflecting the major
steps of the implemented Exercise. Based upon the basic theoretical
considerations, the results obtained should be presented as a table and further
discussed in terms of the established regularities in the water color formation
under different conditions of CPA concentrations. The report should be closed
with the main corollaries/conclusions.
– Table 17.2 is an example of the table you need to generate as a result of the
teaching lab performance. The report should be stored on the network drive.
