Whenever there is a boundary between two different surfaces, light is refracted because there is a change in the speed of light when it crosses from one material to another. The direction in which it ...

A research team has developed a new way to measure and predict how plant leaves scatter and reflect light, revealing that ...

A group of physicists from Russia, Sweden, and the U.S. has demonstrated a highly unusual optical effect: They managed to "virtually" absorb light using a material that has no light-absorbing capacity ...

Infrared spectroscopy (IRS) is a technique used to analyze individual substances in isolation or a mixture, using their spectral information. IRS is based on the measurement of the wavelength and ...

A method for measuring light absorption throughout the ultraviolet and visible regions of the electromagnetic spectrum is known as ultraviolet-visible (UV-Vis) spectrophotometry. Incident light can ...

IN the whole realm of biological science there is perhaps no phenomenon of greater fundamental importance than that exhibited by green plants in the transformation of carbon dioxide and water into ...
