How is visible spectroscopy used to analyze the visible spectrum of light and what information can be obtained from it?
Visible spectroscopy is a technique used to analyze the visible spectrum of light by measuring the absorption or emission of light by a sample. By studying the wavelengths of light absorbed or emitted by a substance, scientists can identify the chemical composition, concentration, and physical properties of the sample. This information can be used to determine the presence of specific compounds, quantify their amounts, and understand their interactions in various materials.
