HERTZIAN WAVES Meaning and
Definition
-
Hertzian waves, also known as electromagnetic waves or radio waves, refer to the oscillating and propagating electrical and magnetic fields that are associated with the transmission of electromagnetic radiation through free space or a vacuum. Named after the German physicist Heinrich Rudolf Hertz, who first demonstrated the existence of such waves in the late 19th century, Hertzian waves encompass a broad spectrum of frequencies, ranging from extremely low frequencies (ELF) to extremely high frequencies (EHF).
These waves are a form of non-ionizing radiation, meaning they do not have enough energy to remove electrons from atoms or molecules. They are characterized by their wavelength and frequency, with wavelength representing the distance between consecutive crests or troughs of the wave, and frequency denoting the number of complete cycles of the wave that occur in one second.
Hertzian waves are extensively used in various applications such as radio and television broadcasting, wireless communication, radar systems, and satellite communications. They are generated through the use of antennas, which produce a changing electric field that propagates through space. Upon reaching a receiving antenna, these waves induce an alternating current in the conductor, which is then converted into useful signals.
Due to their ability to transmit information wirelessly over long distances, Hertzian waves have revolutionized the way humans communicate and access information. They have become an integral part of our modern technological landscape, allowing for the seamless exchange of information across the globe.

Etymology of HERTZIAN WAVES
The term "Hertzian waves" is derived from the name of the German physicist Heinrich Hertz, who made significant contributions to the understanding of electromagnetic waves in the late 19th century. Heinrich Hertz conducted experiments to prove the existence of electromagnetic waves predicted by James Clerk Maxwell's theory of electromagnetism. He demonstrated that these waves could be transmitted and received through space, leading to the development of wireless communication systems. In recognition of his groundbreaking work, the unit of frequency, "hertz" (abbreviated Hz), was named after him. Thus, "Hertzian waves" refers to the electromagnetic waves discovered and studied by Heinrich Hertz.
