Explain the science and technique of spectroscopy. Include the contributions of Isaac Newton, Joseph von Fraunhofer, and Gustav Kirchoff to spectroscopy.

Answer 1

The English philosopher Roger Bacon (1214 – 1294) was the first person to recognize that sunlight passing through a glass of water could be split into colors.

Nearly four centuries later, Sir Isaac Newton coined the term “spectrum” to describe the rainbow of colors produced by sending sunlight through a prism. In 1666, he directed a beam of sunlight through a glass prism and noted the light from the Sun was composed of a continuous spectrum of colors. Newton was not equipped to study the spectrum and was unable to observe the spectrum in more detail. Later, using a telescope and prism, Newton viewed the light from Venus. Again, he noted the light contained a continuous spectrum. Newton’s work with spectral light was not broadly recognized, and little additional work on the nature of spectra was done for 150 years.
