Hello,
I have a prac coming up related to Spectroscopy and using the Beer-Lambert Law. We need to graph absorbance vs. concentration for a chose solution at two different wavelengths (max & 510nm) and compare and comment on the magnitude of molar absorption coefficients determined at these wavelengths. I know the graph at maximum wavelength produces a steeper gradient (Has a higher absorbance than at wavelength 510nm). Why is this the case? A detailed explanation would be ideal.
Thanks!

Beer’s Law Objective : We will explore an application of absorption spectroscopy using calibration curves and Beer’s Law. Use the “LAB : HOW TO…” link from the class website if you need help with how to use balance, Bunsen burner… and such. Introduction: You may write this information in your lab notebook for your own reference. It can’t be cut and pasted. Different solutions have different spectral properties. In this portion of the experiment those properties will be utilized to...
