Like all specrophotometric methods, UV/visible spectrometry is quick and simple to perform, and gives quick results. It can also detect impurities. It is cheap to perform once the equipment is bought.
UV and visible spectroscopy is easy and cheap for drug characterization. It is hence often used for drug characterization.
Ultraviolet and the infrared.
== Fluorescence== Fluorescent objects emit visible light when stimulated by ultraviolet light.
There are an infinite number of wavelengths above visible, below visible, and within visible. Since reality has infinite resolution, we can imagine varying the wavelength with infinite division. To call out bands of wavelength: Ultraviolet, X-rays, & Gamma rays.
UV Visible spectrophotometer measures the response of a sample to ultraviolet and visible range of electromagnetic radiations. Molecules and atoms have electronic transitions while most of the solids have inter band transitions in the UV and Visible range. It operates by passing a beam of light through a sample and measuring the intensity of light reaching a detector.
Ultraviolet radiation is of higher energy than visible light. Ultra-violet suggests that it is above violet in the spectrum, and the colour violet is the uppermost region of visible light.
The fact that all elements have a unique set of colors they emit when stimulated.

All visible wavelengths are longer than the wavelength of ultraviolet.
No
Spectroscopy is basically the study of the spectrums of visible and non-visible light rays. Specifically, it is determining the output of radiation an object has along the spectrum. This is called a wavelength.
Ultraviolet light is not visible. Many ultraviolet lamps also emit some visible light along with the ultraviolet, typically visible violet. Also, ultraviolet light is an ionizing radiation, and will cause some flourescent materials to emit various visible wavelengths of light.

No, the visible part is called visible light. Ultraviolet is invisible to the human eye.
