Rádiofrekvenciás

Rádiofrekvenciás refers to radio frequency, a range of electromagnetic wave frequencies that lie between audio frequencies and infrared radiation. This portion of the electromagnetic spectrum is commonly used for broadcasting, telecommunications, and various technological applications. The frequencies typically range from about 3 kilohertz to 300 gigahertz.

Radio waves are generated by oscillating electric charges and can travel through vacuum and various media. Their behavior and characteristics, such as wavelength and propagation, depend on their specific frequency. Lower frequencies tend to travel longer distances and can penetrate obstacles more effectively, while higher frequencies are more directional and can carry more information.

In broadcasting, radio frequencies are used to transmit audio signals to receivers. This is the basis of AM and FM radio. Telecommunications heavily relies on radio frequencies for mobile phone communication, Wi-Fi, satellite communication, and radar systems. Medical applications include radiofrequency ablation, used to treat certain medical conditions by heating tissue. Industrial uses include microwave heating and industrial heating processes. The spectrum is carefully regulated by international bodies to prevent interference between different services.
