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.
Wavelength in Millimetresmm
Target UnitWavelength in millimetres (mm) is a unit of measure representing the spatial period of a periodic wave, specifically the distance between successive points of equivalent phase, such as crest to crest or trough to trough. In the electromagnetic spectrum, different wavelengths correspond to different types of radiation, from radio waves to gamma rays. The wavelength is inversely related to frequency; as frequency increases, wavelength decreases. The millimetre is a metric unit equal to one-thousandth of a metre, making it a suitable measure for wavelengths of infrared and microwave radiation. In scientific contexts, it is essential for calculations involving wave behavior, interference, and diffraction.
Current Use
Wavelength in millimetres is extensively used in various scientific and engineering disciplines, particularly in the fields of optics, telecommunications, and radar technology. In optics, wavelengths in the infrared range (typically between 0.7 mm to 1 mm) are crucial for thermal imaging and night-vision devices. In telecommunications, microwave frequencies around 1 mm are significant for wireless communication technologies, including Wi-Fi and radar systems. Countries such as the United States, Japan, and members of the European Union utilize millimetre wavelengths for industrial and research applications, especially in the development of advanced materials and medical imaging technologies. The precision of measurements in millimetres allows for accurate design and testing of optical components and systems, enhancing both performance and reliability in practical applications.
Fun Fact
The wavelength of visible light ranges from approximately 0.4 mm (violet) to 0.7 mm (red).

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 wavelength has roots in the early studies of wave phenomena, particularly in the context of sound and light. In the early 19th century, scientists such as Thomas Young conducted experiments that demonstrated the wave nature of light, leading to the understanding of wavelength as a fundamental property of waves. The specific measurement in millimetres emerged with the standardization of metric units in the 18th century, particularly during the French Revolution, when the metric system was developed to provide a universal measurement system. The millimetre became widely accepted in scientific literature as a convenient unit for measuring wavelengths in the electromagnetic spectrum, especially for infrared and microwave applications.
Etymology: The term 'wavelength' is derived from the combination of 'wave', referring to the periodic motion of energy, and 'length', indicating measurement.
