Pronunciation: [pˈa͡ɪ͡ətə zˈiːmən] (IPA) 
"Piter Zeeman" is the correct spelling of the Dutch physicist's name. The first name "Piter" is pronounced as /ˈpi.tər/ with emphasis on the first syllable. The surname "Zeeman" is pronounced as /ˈzei.mɑn/, with the "Z" sounding as "ZAY" and "man" pronounced as "MAHN." Pieter Zeeman is known for his research that led to the discovery of the Zeeman effect, which involves the splitting of spectral lines in a magnetic field.
Pieter Zeeman was a Dutch physicist born on May 25, 1865, in Zonnemaire, Netherlands, and passed away on October 9, 1943, in Amsterdam, Netherlands. He is best known for his discovery of the Zeeman effect, which demonstrates the splitting of spectral lines under the influence of a magnetic field.
The Zeeman effect is a fundamental phenomenon observed in atomic and molecular spectroscopy. It occurs when an external magnetic field is applied to a source of light or electromagnetic radiation, resulting in the splitting of spectral lines into multiple components. This discovery provided significant evidence for the quantized nature of atomic energy levels and played a crucial role in the development of quantum mechanics.
In recognition of his groundbreaking work, Pieter Zeeman was awarded the Nobel Prize in Physics in 1902, jointly with Hendrik Lorentz. Their collaboration led to the formulation of the Lorentz force law and provided a deeper understanding of the electromagnetic forces acting on charged particles moving through a magnetic field.
Aside from his contributions to the Zeeman effect, Pieter Zeeman worked on various other areas of physics, including studies on the behavior of crystals and investigations into the characteristics of surface tension. He served as a professor of physics at the University of Amsterdam and contributed significantly to the advancement of scientific knowledge in his field.
