SPECTRUM ANALYSIS Meaning and
Definition
-
Spectrum analysis refers to a process used to examine and study the composition and characteristics of a given phenomenon or substance by analyzing its electromagnetic spectrum. It involves the separation and identification of different wavelengths or frequencies present in the electromagnetic radiation emitted, absorbed, or reflected by the subject under investigation.
In practice, spectrum analysis involves the use of specialized instruments and techniques to break down the electromagnetic radiation into its constituent wavelengths or frequencies. This is typically achieved using devices such as spectrometers or spectrophotometers, which can measure the intensity of radiation at various wavelengths.
By analyzing the spectrum of the radiation emitted by a substance or phenomenon, scientists and researchers can gain valuable insights into its chemical composition, physical properties, or behavior. Spectrum analysis finds applications across a wide range of scientific disciplines, including chemistry, physics, astronomy, and biology.
For instance, in astronomy, spectrum analysis is employed to study the composition and temperature of celestial objects by analyzing the light they emit or absorb. In chemistry, it helps in the identification and characterization of elements and compounds based on their unique spectral signatures.
Overall, spectrum analysis plays a pivotal role in scientific research and provides essential tools for understanding the fundamental properties and behavior of various substances and phenomena.

Etymology of SPECTRUM ANALYSIS
The term "spectrum analysis" has its roots in two main components: "spectrum" and "analysis".
The word "spectrum" comes from the Latin term "spectrum", meaning "appearance" or "apparition". It was commonly used to refer to an image or an apparition that appeared to be ghost-like. In the context of science, the term was first used by Isaac Newton in his book "Opticks" (1704) to describe the divided colors created by the passing of white light through a prism.
The word "analysis" comes from the Greek term "analusis", which means "dissolution" or "loosening". It refers to the process of breaking down a complex whole into its constituent parts to understand its nature or properties.
When combined, "spectrum analysis" refers to the study or investigation of the constituent parts of a spectrum.
