Today's enhanced scientific and technological development brings a wide range of musical, video, and phonebased pleasures to wherever you are, anytime. However, there is a type of pleasure that has been a vital component of humanity's spiritual diet for centuries on radio. That's radio. The radio (receiver, radio, radio) is a familiar item to us Vietnamese, from children with the program "good night", to adults with "good night" program. news programs or "reading stories late at night." Radio is also a tool for work, such as a driver's wing with a "traffic radio" channel. Radio waves or radio waves are electromagnetic radiation with a longer range than infrared light, frequencies from 3 kHz to 300 GHz. Radio waves travel at the speed of light, and in nature they're produced by thunder.radio is a radio receiver (radio machine) - an electronic device that amplifies, restores, and outputs modulated sound waves. to speak. The radio was developed by three distinct inventions: the radio, the telegraph, and the telephone. These three technologies merged to develop a wireless telegraphy recording method that was initially named "wireless telegraphy". Many inventors have tried to employ many wireless transmission methods, including electromagnetic induction and ground reflection, in order to produce radio waves. However, the radio was developed using electromagnetic waves - a type of electromagnetic radiation that could transmit music, voice, images, and data throughout the world. Radios, microwave ovens, cell phones, remotes, television sets, and other devices use electromagnetic waves with various frequencies to perform distinct functions. Radio waves have frequencies between 3 Hz (very low frequency (VLF) and 300 GHz (EHF). In order to understand the function of electromagnetic waves in this field research, we have studied electromagnetic waves produced by a radio. Some students have completed their studies by experimenting with radio sets from the beginning of the 19th century. They were motivated to understand the relationship between electricity and radio waves by examining whether or not electromagnetic waves were produced by radio. Alessandro Volta developed methods for generating radio waves in order to study the nature of electricity. Gian Domenico Romagnosi utilised the technique of studying electromagnetic waves and their connection with electricity in the same way as Francesco Zantedeschi used the spectroscope to study the nature of light and how it relates to electricity and magnetism. Despite his research, it was not recognised. The problem was solved in the nineteenth century by the invention of radio, which was further developed by Alessandro Volta. Francesco Zantedeschi's work was only recognised after he died in 1829. Michael Faraday realized that electromagnetic induction could exist in 1831. He proved this using experiments and a mathematical model of Faraday's law. electromagnetic forces can be spread around conductors, according to Faraday's law. According to previous research, Joseph Henry performed an experiment to show that magnetic forces could act from a height of 61 meters in 1832. He discovered that alternating currents had oscillating forces with frequencies that decreased in proportion to the oscillation frequency. In 1861, based on the work of other scientists, Maxwell developed electromagnetic wave theory, which was published in the royal scientific journal as "dynamic theory of electric fields". He unified important concepts in modern physics, including electricity, magnetism, and light, with Maxwell's equations. Despite being not the inventor of radio waves, this theory laid the foundation for radio waves as well as today's radio. If you want to listen to online radio, please visit: radiofmluisteren
