Spectroscopy is a powerful tool to identify elements by analyzing how they interact with light. Each element emits or absorbs light at unique wavelengths, creating a “fingerprint” called a spectral signature. For beginners, start with emission spectroscopy using a simple spectroscope or flame test. Here's a summary of the three major types: Absorption/Transmission Spectroscopy measures light absorbed. Spectrometers are powerful instruments used to analyze the properties of light and matter, making them indispensable tools in various fields, including chemistry, physics, biology, and environmental science.
