Radio Waves

Radio waves are electromagnetic wave vibrations that generate different signals by changing the modulation, which can be converted into information such as sound, video or digital communication. When these waves pass through the conductor, an alternating current is generated and this can be converted into useful information. As can be seen from the above figure, radio waves are electromagnetic waves with wavelengths between 1 mm and 10 mm. It is converted to the frequency range from 300 GHz to 30 Hz respectively.

The wavelength of radio waves is about 103 meters. As its name suggests, radio waves are transmitted via radio, TV, and even mobile phones. Radio energy level is lowest. Radio waves are used for remote sensing, where the hydrogen in the universe radiates radio energy at low frequencies and is collected as radio waves. They are also used in radar systems that emit radio energy and collect bounce energy. Particularly suitable radar systems for meteorology are used to predict weather patterns by mapping the surface of the earth as radio energy can easily break through the atmosphere. ;

Radio waves are electromagnetic waves, microwaves, infrared rays, X-rays, gamma rays. The most famous radio waves are used for communication; televisions, mobile phones, and radios all receive radio waves and convert them into mechanical vibrations with speakers to produce audible sound waves. Electromagnetic radiation is transmitted by waves or particles of different wavelengths and frequencies. This wide range of wavelengths is called electromagnetic (EM) spectroscopy. Spectra are usually divided into seven areas in order of decreasing wavelength and increasing energy and frequency. Common names are radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays, gamma rays.

Electromagnetic waves are electromagnetic radiation whose wavelength of the electromagnetic spectrum is longer than the wavelength of infrared light. Radio frequency is 300 GHz maximum and 30 Hz minimum. For 300 GHz, the corresponding wavelength is 1 mm and 30 Hz is 10,000 km. As with all other electromagnetic waves, radio waves move at speed of light. They are generated by charges that undergo acceleration, such as currents that change over time. Naturally occurring radio waves are emitted by thunder and astronomical objects.

Radio waves are one of many types of electromagnetic waves that propagate in the electromagnetic spectrum. Radio waves can be defined by its frequency (Heinich Hertz, which generates electric waves electronically at first). This is determined by the wavelength as follows, depending on the number of times it goes through one cycle per second. Distance (meter) from one peak to the next. The radio frequency is measured in kilohertz, megahertz, gigahertz. (1 kHz = 1000 Hz: 1 megahertz = 106 Hz, 1 GHz = 109 Hz). All radio waves are in the frequency range of 3 kHz, or the frequency range from 3000 cycles per second to 30 GHz. In the frequency range, the radio waves are further divided into two groups or frequency bands such as very low frequency (VLF 10 to 30 kHz), low frequency (LF 30 to 300 KHz), intermediate frequency (MF 300 to 3000 KHz), high frequency (HF 3) . - 30 MHz and VHF (VHF 30-300 MHz)
