HertzHz
Source UnitThe hertz (Hz) is the standard unit of frequency in the International System of Units (SI), representing the number of cycles of a periodic phenomenon occurring in one second. It is defined as one cycle per second and is utilized to quantify oscillations, waves, and repetitive events in various fields, including physics, engineering, and telecommunications. The hertz encompasses a wide range of frequencies, from extremely low frequencies in the audible spectrum to extremely high frequencies in radio and microwave domains. The unit is named after Heinrich Hertz, a German physicist who made significant contributions to the study of electromagnetic waves. His pioneering experiments in the late 19th century led to the foundational understanding of wireless communication, making the hertz a pivotal unit in both theoretical and applied physics.
Current Use
The hertz is widely utilized across various industries, including telecommunications, audio engineering, and medical equipment. In telecommunications, frequencies are crucial for the transmission of data and signals, with radio frequencies ranging from 3 kHz to 300 GHz being used for broadcasting and wireless communication. In audio engineering, sound frequencies are measured in hertz, with the human auditory range typically between 20 Hz and 20 kHz, impacting music production and sound design. Additionally, in medical imaging, techniques such as MRI utilize radio frequency signals measured in hertz to create detailed images of the body. Countries around the world, including the United States, Germany, and Japan, employ the hertz in various applications, ensuring uniformity in frequency measurements essential for technology and scientific research.
Fun Fact
The hertz is named after Heinrich Hertz, who was the first to conclusively prove the existence of electromagnetic waves.
ExahertzEHz
Target UnitThe exahertz (EHz) is a unit of frequency in the International System of Units (SI), representing one quintillion hertz or 10^18 hertz. It is used to quantify phenomena occurring in very high frequency ranges, such as in advanced telecommunications, quantum computing, and electromagnetic radiation. An EHz denotes cycles per second at an immense scale, making it particularly relevant in fields that deal with processes occurring at the speed of light or in atomic and subatomic particles. The exahertz is often used in scientific research to describe the frequencies of electromagnetic waves, such as gamma rays and certain types of laser light, which can reach these extraordinarily high frequencies.
Current Use
The exahertz is primarily used in advanced scientific research and telecommunications. It is particularly relevant in fields such as quantum computing, where processes can occur at frequencies approaching exahertz levels. In telecommunications, the need for high-frequency transmission has led to the exploration of exahertz waves for future technologies, including next-generation wireless communication systems that could leverage these frequencies for faster data transfer. Countries like the United States, Germany, and Japan are at the forefront of research utilizing exahertz frequencies, particularly in quantum optics and high-energy physics, where accurate frequency measurements are crucial. Furthermore, exahertz is also significant in understanding and measuring electromagnetic radiation frequencies, such as those emitted by certain types of cosmic events.
Fun Fact
Exahertz frequencies are beyond the capabilities of traditional electronic devices, pushing research towards optical technologies.

His pioneering experiments in the late 19th century led to the foundational understanding of wireless communication, making the hertz a pivotal unit in both theoretical and applied physics.
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 concept of frequency has been studied since ancient times, but the term 'hertz' was established in honor of Heinrich Hertz (1857-1894), a German physicist who made significant contributions to the understanding of electromagnetic waves. The prefix 'exa-' was introduced in the late 20th century as part of the International System of Units. It is derived from the Greek word 'hex' meaning six, representing the sixth power of ten, or 10^18. The exahertz unit was officially recognized in the SI in the 1970s, as the need for measuring higher frequencies became increasingly important in various scientific and technological applications.
