Frekvenciasávba refers to a frequency band, which is a range of frequencies within the electromagnetic spectrum. In various scientific and technological fields, specific frequency bands are designated for particular purposes. For example, in telecommunications, different frequency bands are allocated for radio, television broadcasting, mobile phone services, and Wi-Fi. These allocations are crucial for managing the electromagnetic spectrum efficiently and preventing interference between different services.

The electromagnetic spectrum is broadly divided into radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays, each encompassing a wide range of frequencies. Within these broader categories, narrower frequency bands are defined and utilized. The size and location of a frequency band are determined by its lower and upper frequency limits. For instance, the AM radio band typically ranges from 530 kHz to 1710 kHz.

In physics and engineering, understanding and utilizing specific frequency bands is fundamental. This includes applications like spectroscopy, where different molecular structures absorb and emit radiation at characteristic frequencies, allowing for their identification and analysis. In radar systems, specific frequency bands are chosen based on factors such as atmospheric penetration, resolution, and the desired range of detection. The concept of a frequency band is therefore essential for the design, operation, and regulation of a vast array of technologies and scientific investigations.
