EM Waves for TV and Radio

Electromagnetic waves are used for transmitting TV and radio signals. These waves have a specific frequency range that is suitable for broadcasting. Let's understand the frequency range of EM waves used for TV and radio.

Frequency Range for TV

- TV signals are transmitted using electromagnetic waves in the VHF (Very High Frequency) and UHF (Ultra High Frequency) bands.
- The frequency range for VHF is 54 MHz to 216 MHz, and for UHF, it is 470 MHz to 890 MHz.
- The frequency band used for a particular TV channel is allocated by the government regulatory body.

Frequency Range for Radio

- Radio signals are transmitted using electromagnetic waves in the AM (Amplitude Modulation) and FM (Frequency Modulation) bands.
- The frequency range for AM is 535 KHz to 1605 KHz, and for FM, it is 88 MHz to 108 MHz.
- The frequency band used for a particular radio station is allocated by the government regulatory body.
