SPECTRUM LINE Meaning and
Definition
-
A spectrum line is a term used in physics and spectroscopy to describe a specific wavelength or frequency of electromagnetic radiation that is emitted or absorbed by atoms, molecules, or other particles. It is also known as an emission or absorption line.
When a sample of material is subjected to energy, such as heat or light, the atoms or molecules in the sample absorb or emit energy in specific discrete amounts. This energy is emitted or absorbed in the form of electromagnetic radiation, such as visible light, infrared, ultraviolet, or radio waves.
The spectrum lines appear as narrow bands or lines when the emitted or absorbed radiation is dispersed using a prism or a diffraction grating. These lines are unique to each element or compound, serving as an identifying characteristic. By examining the position and intensity of these lines, scientists can determine the chemical composition, temperature, density, and other relevant properties of the sample.
The spectrum lines are directly related to the transitions of electrons within atoms or molecules. These transitions occur when electrons move between different energy levels. Each energy transition corresponds to a specific wavelength or frequency of radiation, resulting in the appearance of distinct lines on the spectrum.
The study and analysis of spectrum lines have played a crucial role in the field of spectroscopy, aiding scientists in various disciplines to understand the fundamental properties of matter and unravel the mysteries of the universe.

Etymology of SPECTRUM LINE
The word "spectrum line" is composed of two terms: "spectrum" and "line".
The term "spectrum" originated from the Latin word "spectrum", which means "appearance" or "apparition". It first entered English in the early 17th century and referred to a broad range of colors seen when light is dispersed or separated, such as when passing through a prism or raindrops. The word "spectrum" later became associated with the visible light spectrum, consisting of various colors ranging from red to violet.
The term "line" has its roots in the Old English word "līne", which can be traced back to the Latin word "linea", meaning "string" or "cord". In this context, "line" refers to a linear mark or stroke.
