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.

Where can one compare CCTV price?
CCTV, otherwise known as Close Circuit Television, uses video cameras to transmit signals to specific monitors. Comparing prices for a CCTV set-up can be made at Nextag and Consumer Reports.
What method of signal transmission uses radio waves to carry signals?
The analog method of signal transmission uses radio waves to carry signals. Digital transmission involves the use of satellites to transmit signals.
What are some uses of satellites orbiting the earth?
The difference is in the tilt of the plane of the orbit relative to the Earth's equator, which is zero for geostationary and 90 degrees for polar-orbit.
Why did Congress order the change to digital TV?
Mainly to free up radio frequency spectrum. An analog picture uses 4.5 megahertz for the video and sound and a satellite transponder is typically 8 Mhz. wide. With the new digital system, it's possible to transmit up to eight separate TV channels in the same bandwidth on the transponder using a system called, `multiplexing`.
The smartball technology being developed by Adidas for use in sports equipment uses which technology to transmit signals?
kos is good
Can the human body transmit outside the body?
It depends on what you mean by "transmit". Our nerves and muscles use electrical signals. These signals can be detected outside the body. The biochemical processes in each cell uses energy. This energy can be detected outside the body as heat.
What uses are there for parabolic mirrors?
Parabolic mirrors are formed in a dish like shape, the purpose of it's shape is to transmit the electromagnet waves. For example when using a microwave or watching a television, it is through electromagnet radiation that make it possible to function. Television receives the signals via the satellite dish, the satellite dish acts as the parabolic mirror.
How does High Definition television work as opposed to the old technology?
High Definition television uses digital signals which are more compact. The old technology (standard definition) uses analog signals which take up more space. So because the HDTV signals are more compact, they are allowed to carry a lot more information and therefore provide a clearer picture.
Different between fiber optical cable and copper cable?
Fiber optic cable is constructed out of glass or plastic, and uses light pulses to transmit data. Copper cable is made out of copper material (not glass or plastic) and uses electrical voltages to transmit signals.
What is the difference between Dish Network and cable network?
cable tv is expensive cable tv has a fixed number of transmitted signals with cable tv, the number of channels lowers the quality of picture and sounds cable tv is expensive
What uses a digital signal?
Many television stations have been using digital signals for at least 30 years. They turned them into analog signals at the antenna for broadcast. Now they are simply leaving them in their original form.
What are the uses of hydroelectric?
Anything that uses electricity. Hydroelectric energy is just energy created by water spinning turbines which uses giant capacitors to store and transmit energy. things: lighting houses, appliances, street lights, computers, TVs, ect....anything that uses electricity
