Television technology is based mainly on the manipulation of the electro- magnetic spectrum.
Televisions do not transmit signals, they receive them. The question sounds like a school question and therefore it would not be beneficial to simply answer the question entirely. Televisions receive electromagnetic signals. Research of the electromagnetic spectrum will provide results. For guidance, so some research on "cathode ray tubes" which are the older glass tube televisions. Rays are not transmitted but reading about CRTs will provide a useful answer. Additionally, televisions of all type emit light which can be considered a ray. Once again, research on the electromagnetic spectrum will provide some information that might be useful.

yes so is am fm radio and tv signals
Electromagnetic waves, specifically radio waves, are commonly used for broadcasting purposes. These waves are able to travel long distances and pass through buildings and other obstacles, making them ideal for broadcasting television and radio signals.
A DTV antenna is used to capture digital television signals. By law, all television signals in the United States must be digital, and this type of antenna is used by customers who do not subscribe to satellite or cable services.
The type of electromagnetic wave used for TVs is radio waves. Specifically, TV signals are carried on radio frequencies within the electromagnetic spectrum.
Satellite TV uses microwaves, which are a type of electromagnetic wave. These microwaves travel between the satellite in space and a receiver on the ground to transmit television signals.
Communications Satellites ************************ Electro-magnetic waves. Carrier waves.

A TV remote control typically uses infrared radiation as the type of electromagnetic wave to send signals to the TV. The infrared light emitted from the remote control carries the coded signals that are received by a sensor on the TV, allowing for wireless communication to change channels, adjust volume, or control other functions.
HDMI is a physical interface for television signals. Physical means that it defines the connectors, cable, voltages and currents. Within the framework of the physical interface there are numerous options for the type of content that can be sent. Although HDMI was designed to carry high definition television signals it operates with standard definition signals as well. The limitations of signals on HDMI interfaces is set by the source and the receiver, i.e. the player or television. Each device can handle certain signals and normally they will be listed in the operating manual.
Radio waves are the type of electromagnetic wave that carries television and radio signals. They have longer wavelengths than microwaves and shorter wavelengths than infrared waves.
