UV-Vis spectroscopy

Spectroscopy is an analytical technique used to identify the composition and determine the structure of chemical species by studying the light they emit, transmit, or absorb. UV-Vis spectroscopy studies the production of and interactions with light in the ultraviolet and visible regions of the electromagnetic spectrum.

Use Your Smartphone as an "Absorption Spectrophotometer"
// Wednesday, March 30, 2016 • Tom Kuntzleman
A smartphone can be used in a remarkably simple and inexpensive way to teach your students about absorption spectroscopy and Beer’s Law. In short, light reflected off of colored construction paper is passed through a sample and detected by an RGB application on a smartphone.
