Yes, both TV signals and radio signals travel at the speed of light in a vacuum, which is approximately 299,792,458 meters per second (or about 186,282 miles per second).
TV signals and radio signals are both forms of electromagnetic radiation, which means they propagate through space as waves. Electromagnetic waves, including visible light, radio waves, and other forms of radiation, all travel at the same speed in a vacuum, commonly referred to as the speed of light. This speed is a fundamental constant in physics.
When you watch television or listen to the radio, the signals carrying the information are transmitted as electromagnetic waves. These waves are generated by the broadcasting station and travel through the air or space to reach your receiving antenna or device. The speed at which these signals propagate is essentially the speed of light, although it can be slightly slower in other mediums, such as through cables or fibers, due to factors like the refractive index.
So, whether it's a TV signal, a radio signal, or any other form of electromagnetic radiation, they all travel through space at the speed of light.
