ultraviolet spectrum
Definition
Noun: The range of wavelengths of ultraviolet radiation, typically considered to be from about 10 nanometers to 400 nanometers, lying between the visible light spectrum and X-rays in the electromagnetic spectrum.
Usage
The term "ultraviolet spectrum" refers specifically to the complete range of ultraviolet (UV) radiation, often analyzed by its effects or its position within the broader electromagnetic spectrum. * Scientists study the ultraviolet spectrum to understand solar radiation and its impact on Earth's atmosphere. * The ozone layer absorbs much of the harmful portion of the sun's ultraviolet spectrum.
Advanced Usage
- In Astronomy: Used to analyze celestial objects, as observations in the ultraviolet spectrum can reveal hot stars and interstellar gas.
