In this post, we&#8217;ll look at the science behind UV light, its many applications, and how to create equipment that utilizes it.<\/p>\n<p>We&#8217;ll take a look at some common UV light methods and applications.

The interaction of light and matter is the foundation of spectroscopy.<\/p>\n<p>Transmission, absorption, reflection, and scattering can occur when a substance is exposed to an electromagnetic wave. When the energy difference (E) between a molecule&#8217;s ground and excited states equals the energy difference (E), absorption occurs. An electronic transition is the excitation of an electron from its ground state to its excited state.<\/p>\n<p><img loading=\"lazy\" class=\"alignnone wp-image-667919 size-full\" src=\"https:\/\/infinitylearn.com\/surge\/wp-content\/uploads\/2023\/08\/Principle-of-UV-visible-spectroscopy.png\" alt=\"Principle of UV visible spectroscopy\" width=\"571\" height=\"246\" srcset=\"https:\/\/infinitylearn.com\/surge\/wp-content\/uploads\/2023\/08\/Principle-of-UV-visible-spectroscopy.png 571w, https:\/\/infinitylearn.com\/surge\/wp-content\/uploads\/2023\/08\/Principle-of-UV-visible-spectroscopy-300x129.png 300w\" sizes=\"(max-width: 571px) 100vw, 571px\" \/><\/p>\n<p>The Planck equation describes the link between energy differential and wavelength.<br \/>\nE=hv=hc\/\u03bb<\/p>\n<p>Principle of UV spectroscopy slideshare<\/p>\n<p>The fundamental property of absorption known as Beer-Lambert&#8217;s law underpins UV Visible spectroscopy.
