When would you use an absorbance graph?

An absorbance graph is used to analyze how much light is absorbed by a sample at various wavelengths, which helps identify the concentration of a substance in a solution. This is particularly useful in fields like chemistry and biochemistry for determining the concentration of colored compounds, such as in spectrophotometric assays. Additionally, absorbance graphs can aid in studying the properties of materials and understanding chemical reactions by observing changes in absorbance over time.
