"Spectrum" Natural Recordings by Native Speakers
A spectrum is a range of colors or frequencies that are visible, audible, or measurable, especially a range between two limits or boundaries.
Derived from the words "spectral" (relating to light that is separated into its component colors by a prism) and "photometer" (an instrument used to measure the intensity of a beam of light). Therefore, spectrophotometrical refers to the process of measuring the interaction between light and matter, particularly in the analysis of the absorption, reflection, or transmission of light by a substance.<br><br>In other words, it is a technique used to determine the concentration of a specific substance in a sample by measuring the amount of light absorbed or transmitted through it.
A spectroscope is an optical device used to split light into its component colors, which are known as a spectrum. It is used to analyze the light emitted or absorbed by a sample, typically atoms or molecules, to identify the elements present and their concentrations. The term can also refer to the process of using a spectroscope.
A spectroscopist is a scientist who studies the interaction between matter and electromagnetic radiation, such as light, to determine the composition and properties of materials. Spectroscopists use various techniques, including spectroscopy, to analyze the characteristics of objects, substances, or phenomenon and interpret the light or other forms of electromagnetic radiation that is emitted or absorbed by them.
verb: to form or express an idea or explanation that is not based on fact or direct evidence, but on guesswork or hypotheses. <br><br>Example: "Several people have speculated that the company will make a profit next year."
