ARC SPECTRUM Meaning and
Definition
-
An arc spectrum refers to the unique set of electromagnetic radiation emitted by an electric arc discharge. It is characterized by a series of distinct and bright lines or bands that correspond to specific wavelengths or frequencies. This emission spectrum arises due to the presence of excited atoms or ions in the arc.
When a high voltage is applied across a gap between two electrodes, an electric arc is generated, which is a type of electrical discharge. This discharge creates a high temperature plasma consisting of ions, electrons, and excited atoms. The energy generated during the arc causes some of the atoms or ions to transition to higher energy states. As these excited particles return to their ground state, they release excess energy in the form of light or electromagnetic radiation.
The arc spectrum is a valuable tool used in spectroscopy and scientific research to analyze the chemical composition and properties of materials. Each element or compound displays a unique arc spectrum, enabling scientists to identify and study the composition of unknown substances. By comparing the observed emission lines with known spectral patterns, researchers can accurately determine the components of the sample under investigation.
In addition to scientific applications, arc spectra also have practical applications. For instance, the distinctive spectral lines produced by metals in arc lamps are used in various fields like photography, film projection, and street lighting. These lamps provide a steady and intense light source by exploiting the characteristic emission lines of specific metals, resulting in highly efficient and bright illumination.

Etymology of ARC SPECTRUM
The term "arc spectrum" can be broken down into its components to understand its etymology:
1. "Arc": In this context, "arc" refers to a curved line. It comes from the Latin word "arcs", meaning a bow or arc. The term was used historically to refer to the shape formed by an electric arc, which is a luminous discharge of electricity between two electrodes.
2. "Spectrum": This word originated from the Latin "spectrum", meaning "appearance" or "apparition". It subsequently evolved in scientific usage to refer to a range of colors observed when white light is dispersed by a prism or other means into its individual wavelengths.
By combining these two terms, "arc spectrum" refers to the collection of wavelengths or colors that can be observed in the light emitted by an electric arc.
