How do satellites and TV signals work?
Satellite TV Providers transmits the signals through their satellite dish converting it first from digital signals to analog signals. These signals which were converted will be transmitted to the satellite. The satellite will then transmit the analog signals per request of the satellite dish connected to the receiver of the subscriber. Once signals are received, it will be converted back to digital signals which can be read by the receiver and be displayed to the television.
What are electronic signals converted into when transmitted through fiber-optic cables?
Light.
Light x-rays tv signals and ultraviolet rays are examples of?
electromagnetic radiation
What happens to the energy that enters a television but is not converted into light or sound?
It becomes heat. You can feel it at the top of the TV set. All wasted energy is eventually converted to heat.
What is Scientific about watching tv?
The TV is created using science, the shows are recorded using science, even the signals are sent from the TV station to your house using science. If you want to go further, the light being emitted by the tv is traveling through the room to your eye.

What speed are television signals?
A television signal is about the speed of light. or at 3x10 to the power of 8 meters per second
How is wind energy converted into light energy?

What data do infrared satellites use to create image?
They convert infrared radiation into electrical signals which is then converted into visible light.
When you are watching TV electrical energy is being converted into what different forms of energy?
-- sound energy -- light energy -- heat energy
