A "Television Wave" refers to the electromagnetic waves used to transmit television signals. These waves carry audio and visual information from broadcasting stations to televisions in homes. The signals can be transmitted through various methods, including cable, satellite, and over-the-air broadcasting. Television waves operate within specific frequency ranges, typically between 54 MHz and 890 MHz for analog and digital broadcasts. The transition from analog to digital television has improved picture and sound quality, allowing for more channels and better reception. This shift has also enabled the development of high-definition (HD) and ultra-high-definition (UHD) formats.
