monochromatic radiation
Quick Summary
Monochromatic radiation refers to electromagnetic radiation of a single frequency or wavelength. In simpler terms, it's light of one specific color. This is in contrast to polychromatic light, which is composed of multiple wavelengths, like white light.12
Light itself is a form of electromagnetic radiation that exhibits both wave and particle properties. Each beam of light has a specific frequency, wavelength, and energy. The visible spectrum, which our eyes can perceive, ranges from about 400 nanometers (violet) to 700 nanometers (red).1
Monochromatic radiation is crucial in various scientific applications. For instance, lasers produce coherent monochromatic light, which is used in technologies like spectrophotometers for studying light absorption and emission.34
