History & Origin
The concept of frequency has been recognized since the early studies of harmonic motion and waves. The term 'hertz' was adopted in the late 19th century after the work of Heinrich Hertz, who first conclusively demonstrated the existence of electromagnetic waves in 1887. Hertz's experiments validated James Clerk Maxwell's electromagnetic theory, which predicted that light and radio waves travel as oscillating electric and magnetic fields. The significance of Hertz’s work led to the establishment of the hertz as a unit of measurement for frequency in the 1930s, formalized by the International Electrotechnical Commission (IEC) in 1930 and further recognized by the General Conference on Weights and Measures (CGPM) in 1960.
Etymology: The term 'hertz' is derived from the last name of Heinrich Hertz, which was adopted as a unit of measurement in honor of his contributions to electromagnetism.

History & Origin
The petahertz was introduced in the late 20th century as part of a broader effort to standardize units of measurement in accordance with the International System of Units (SI). The prefix 'peta-' is derived from the Greek word 'penta,' meaning five, which denotes the factor of 10^15 (or a quadrillion). The SI system was established to provide a clear and consistent framework for scientific communication, enabling researchers and engineers to share their findings and technologies across different disciplines and geographical boundaries. As technology advanced, especially in telecommunications and computing, the need for larger units of frequency became evident, leading to the adoption of the petahertz as a standard unit.
Etymology: The term 'petahertz' combines the prefix 'peta-', meaning one quadrillion (10^15), with 'hertz,' named after the German physicist Heinrich Hertz, who made significant contributions to the study of electromagnetic waves.
