The Beer-Lambert law is a fundamental principle in quantitative spectroscopy, which states that the absorbance of radiation by a sample is directly proportional to the concentration of the absorbing species and the path length of the radiation through the sample. Spectrophotometer Principle is essential in chemistry and helps students understand various practical and theoretical applications related to this topic. It involves measuring the interaction between matter and electromagnetic radiation, and is widely used in various fields such as chemistry, biology, and pharmaceuticals. In this. Spectroscopy techniques are two types: Qualitative spectroscopy: This technique studied the radiation absorbed or emitted by an atom or molecule which will give information about its identity.
