In 1802 he observed dark lines in the solar spectrum, an important early step in the history of spectroscopy.<br /> <br /> == Solar spectrum ==<br /> Wollaston observed dark lines in sunlight using a prism and a narrow slit. He interpreted them as boundaries between colors rather than as absorption features. [[Biography:Joseph von Fraunhofer|Joseph von Fraunhofer]] later mapped many more of these lines with greater precision, and they became known as Fraunhofer lines.<br /> <br /> Although Wollaston&#039;s observation came before quantum mechanics, spectral lines later became central evidence for discrete atomic energy levels and quantum transitions.<br /> <br /> == Quantum Collection links ==<br /> * [[Physics:Quantum Spectral lines and series]]<br /> * [[Physics:Quantum atoms/transition]]<br /> * [[Physics:Quantum atoms/energy level]]<br /> * [[Physics:Quantum photon]]<br /> <br /> == References ==<br /> {{reflist|3}}<br /> * {{Cite web |title=William Hyde Wollaston |url=https://www.britannica.com/biography/William-Hyde-Wollaston |website=Encyclopaedia Britannica |access-date=2026-05-23}}<br /> * {{Cite web |title=William Hyde Wollaston |url=https://mathshistory.st-andrews.ac.uk/Biographies/Wollaston/ |website=MacTutor History of Mathematics Archive |access-date=2026-05-23}}<br /> <br /> {{Author|Harold Foppele}}</div>
