Which did inventor Borge Bak study at the university of Copenhagen?
Spectroscopy Spectroscopy is the study of the interaction between matter and electromagnetic radiation. Historically, spectroscopy originated through the study of visible light dispersed according to its wavelength, by a prism. Later the concept was expanded greatly to include any interaction with radiative energy as a function of its wavelength or frequency. Spectroscopic data is often represented by an emission spectrum, a plot of the response of interest as a function of wavelength or frequency.
Rasmus Rask Rasmus Kristian Rask (] ; born Rasmus Christian Nielsen Rasch; sometimes rendered as Erasmus Rask; 22 November 1787 – 14 November 1832) was a Danish linguist and philologist. He wrote several grammars and worked on comparative phonology and morphology. Rask traveled extensively to study languages, first to Iceland, where he wrote the first grammar of Icelandic, and later to Russia, Persia, India, and Ceylon (now Sri Lanka). Shortly before his death, he was hired as professor of Eastern languages at the University of Copenhagen. Rask is especially known for his contributions to comparative linguistics, including an early formulation of what would later be known as Grimm's Law.
