UV-visible spectroscopy is an interpretive skill that amplitude the variety of different wavelengths of UV or visible light, which are captivated by or transferred via a pattern new assessment to an implication or blank constituent. This asset is encouraged by way of the pattern combination, doubtlessly subject to network on what is within the representative and at what attention. Because this spectroscopy execution confides on the control of mild. Therefore, illuminate can be described by its wavelength, which can be useful in UV-visible spectroscopy to analyse or identify different substances.

When light falls on a substance, a part of the light that interacts with a substance is absorbed, and the remaining light is either reflected or transmitted through the substance. Colorimetric is used for the detection of dyes, food colourant in which the wavelength of light that different coloured dyes absorb varies. The majority of dyes are conjugated substances with alternate double and single bonds, and they generally absorb light in the visible spectrum. It is used for the food colourant studies due to the long history and widespread use of dyes in retail goods, the spectroscopic identification of food colourings appears to be a viable methodology.
