broadcast frequencies
Broadcast frequencies refer to specific ranges of electromagnetic waves used for transmitting audio and video signals over the air. These frequencies are measured in hertz (Hz) and are divided into bands, such as AM (Amplitude Modulation) and FM (Frequency Modulation) for radio, and VHF (Very High Frequency) and UHF (Ultra High Frequency) for television. Each band has designated frequencies assigned by regulatory bodies to prevent interference between different broadcasters.
Different types of broadcasts operate on various frequencies to ensure clear reception. For example, AM radio typically operates between 530 kHz and 1700 kHz, while FM radio operates between 88 MHz and 108 MHz. Similarly, television broadcasts use VHF channels 2-13 and UHF channels 14-36. Understanding these frequencies helps listeners and viewers tune into their favorite stations effectively.
