Television uses radio waves, specifically a portion of the radio spectrum known as very high frequency (VHF) and ultra high frequency (UHF).

Here's a breakdown:

* Analog TV: Used VHF and UHF radio waves to transmit signals.

* Digital TV: Also uses VHF and UHF radio waves, but the signals are encoded digitally, leading to clearer picture quality and more channels.

It's important to note that while television broadcasts use radio waves, the signals are modulated to carry the video and audio information. This means that the radio waves are altered in a specific way to represent the content being transmitted.
