"Ultraviolet" means "beyond violet" (from Latin ultra, "beyond"), violet being the color of the highest frequencies of visible light. Ultraviolet has a higher frequency (thus a shorter wavelength) than violet …

Although we see sunlight (or white light) as uniform or homogeneous in color, it is actually composed of a broad range of radiation wavelengths in the ultraviolet (UV), visible and infrared (IR) portions of the …

UV (Ultraviolet) Light refers to the region of the electromagnetic spectrum between visible light and X-rays, with a wavelength falling between 400 and 10 nanometers.

Dec 18, 2025 · Ultraviolet radiation is the portion of the electromagnetic spectrum extending from the violet, or short-wavelength, end of the visible light range to the X-ray region.

Apr 1, 2023 · The primary source of UV light is the Sun, which emits radiation across the entire UV spectrum. However, only UVA and UVB radiation reach the Earth’s surface, as the ozone layer …

Jun 19, 2025 · What is ultraviolet light, and where does it come from? Learn how UV radiation is classified, measured, and used in medicine, manufacturing, astronomy, and daily life, plus how to …

Spectroscopy allows the study of how matter interacts with or emits electromagnetic radiation. There are different types of spectroscopy, depending on the wavelength range that is being measured. UV-Vis …

Aug 10, 2016 · The Sun is a source of the full spectrum of ultraviolet radiation, which is commonly subdivided into UV-A, UV-B, and UV-C. These are the classifications most often used in Earth sciences.

The sun emits energy over a broad spectrum of wavelengths: visible light that you see, infrared radiation that you feel as heat, and ultraviolet (UV) radiation that you can’t see or feel.

Aug 4, 2025 · The ultraviolet (UV) spectrum is an invisible segment of light, extending beyond the violet end of the visible spectrum. This electromagnetic radiation surrounds us, originating from both …
