Sunlight reaches the earth as white light, which is made up of all the rainbow colors. Rainbow colors are red, orange, yellow, green, blue, indigo, and violet. It is easy to remember them by using the ...

Spectroscopy is a group of investigative techniques based on matter-light interactions, and Raman spectroscopy is a subcategory focused on the distinct infrared or visible light scattering caused by ...

Researchers have improved a method for probing semiconducting crystals with light to detect defects and impurities. The details of their 'omnidirectional photoluminescence (ODPL) spectroscopy' set-up ...

Throughout the mid-1800s, improvements on the spectroscope allowed physicists to more accurately measure the wavelengths of light and identify new elements—like helium. Wikimedia Commons “I have ...

When we taught a class of first year chem/biochem majors about spectroscopy, we introduced them to it with a task. It was to dig through bins full of the things shown below (many of them 3D-printed ...
