Who invented spectroscopy?

Answer 1

Spectroscopy, as a scientific technique, does not have a single inventor but rather evolved through contributions from multiple scientists. The foundational work began with Isaac newton in the late 17th century when he demonstrated the dispersion of light using a prism. Later, in the 19th century, figures like Gustav Kirchhoff and Robert Bunsen further developed the technique, applying it to the analysis of light from various sources, leading to the establishment of modern spectroscopy.
