Write down the Beer-Lambert law as it applies to neutron radiography. Calculate the attenuation coefficient of hydrogen and iron for thermal neutrons and for 100 KeV X-rays (four attenuation coefficients in total). Show all steps and quote your resources. How will neutron beam attenuation differ between these two materials and between the two types of radiation?

Beer-Lambert law relates the attenuation of light to the properties of the samples in UV-Vis spectrometer; however, in general, the experimental results do not follow the Beer’s law. What are the limitations of Beer’s law?

What are the two most important fundamental limitations of the Beer-Lambert Law?

Use the following information and the Beer-Lambert law to determine the mass of the lycopene extracted and the mass of lycopene per 100 grams of tomato paste. 2mL of lycopene was extracted from 8 grams of tomato pase. This was then diluted to 5mL. 1ml of the diluted solution was withdrawn and then further diluted to 9mL. The UV-vis absorbance at 502nm was determined to be 0.162. The cell path was 1cm.

Use the Beer-Lambert law to explain how a colorimetric assay works in the spectrophotometer. In your answer, define the following terms; chromophore, extinction coefficient, absorbance, transmission and reagent blank. Most of the spectrophotometers in the teaching lab emit light of wavelengths between 400-700nm. However some spectrophotometers also emit light between 200-400nm. Why is this extended range useful? Provide a specific example. How can you use a spectrophotometer to perform a qualitative analysis of a substance?

I need to use Beer's Law to determine a concentration, yet my book states "The Beer-Lambert Law is: A = ε0 b c The terms ε0 (extinction coefficient) and b (path length) are constant under the conditions of this experiment, allowing the further simplification Absorbance α (is directly proportional to) concentration." Would this not then mean that my number for absorbance is always equal to the number of concentration? I know I need to use y = mx + b,...
