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 ...

Learn about color and how to create a spectroscope using simple materials. What is color? Learn about light and wavelengths and what creates color in this episode of Camp GPB. Then learn how to build ...

An ultraviolet photon-counting dual-comb spectrometer. Two ultraviolet frequency combs of slightly different pulse repetition frequencies are generated at very low light levels by nonlinear frequency ...

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 ...

Raman spectroscopy is a non-destructive analytical method that generates complex information about the phase, chemical structure and crystallinity of sample matter. A range of molecular interactions ...

Life for the 19th-century astronomer was kind of monotonous, 200 years after Galileo's revolutionary work with the telescope. Astronomers had carefully tracked the motions of the planets, discovered a ...
