In this experiment you will create two graphs. The first will be absorption vs wavelength and the second, absorption vs concentration. Should either (or both) graph result in a straight line?
Homework Answers
The graph between absorption versus wavelength will not result
in a straight line. It is in the form of peak because absorption of
a sample increases with the increase in the wavelength but to a
certain limit called maximum wavelength (
max). After
max absorption
decreases.
It is used to estimate max so that
sample have maximum absorption.
The graph between absorbance versus concentration result in
straight line because according to Beer's law for dilute solutions
amount of light absorbed at a specific max is directly
proportional to the concentration of solutions. Hence graph result
in a straight line.
A = 
lc
A 
c (directly
proportional) is molar
absorptivity which remain constant for a substance and l is path
length which is also remain constant for a cuvette usually 1 cm

2) Draw two schematic graphs using pencil showing a typical stress-strain curve for aluminum. The first graph should show engineering stress vs engineering strain, and the second graph should show true stress vs true strain. Label the showing: (i) elastic modulus (ii) proportional limit (iii) yield stress (iv) yield strain (v) fracture stress (vi) fracture strain on each graph. You may show both graphs on one plot.

If you were to graph the inverse of the wavelength vs the inverse of the initial energy level squared, what would the shape of the graph be like? A parabola opening up. A parabola opening down. A straight line with negative slope. None of the above. A straight line with positive slope.
