Absorption vs. Absorbance: Difference and Comparison
Edited by Muazma Batool — By Muneeza Rehman — Published on February 13, 2024
Absorption refers to the process of taking in or soaking up, while absorbance is a measure of the amount of light absorbed by a solution.
Difference Between Absorption and Absorbance
Absorption is a general term that denotes the process by which something is taken in, soaked up, or assimilated. It can be used in various contexts, ranging from the absorption of nutrients in biology to the absorption of light in physics. In every scenario, absorption highlights the process or act itself. Conversely, absorbance is a more specific term that finds its primary application in the realm of spectroscopy.

Absorbance, specifically, quantifies the amount of light that a solution absorbs at a particular wavelength. When light passes through a medium, part of it gets absorbed, and the degree to which this happens is represented by absorbance. While absorption provides a broad understanding of the phenomenon, absorbance gives a quantifiable measure, often helping determine the concentration of a solution.

Interestingly, absorption can occur in various domains of life and science. For example, one might discuss the absorption of sound, where certain materials can soak up sound waves, reducing noise. Absorbance, however, remains firmly in the domain of optical measurements, particularly in solutions where light's interaction can tell us about the solution's properties.

Furthermore, while absorption has a broader range of applications and contexts, absorbance, being more specific, is primarily used in labs, research, and industries where understanding light's interaction with solutions is essential. In essence, while both terms revolve around the concept of 'taking in,' absorption is about the action, and absorbance is about the measurement.
