Question

How does UV visible spectroscopy work?

Answer 1

Ultraviolet and visible (UV-Vis) absorption spectroscopy is the measurement of the attenuation of a beam of light after it passes through a sample or after reflection from a sample surface. Absorption measurements can be at a single wavelength or over an extended spectral range.

$\huge\purple{Work of UV -Vis spectroscopy }$

In a cuvette substance is taken and then UV vis Spectrum of different wavelengths are passed or dropped on this sample . And then amount of wavelength and its range is noted .

IF no absorbtion takes place than transmittance is 100%
