Most simplistically, it works on radio waves, invisible wave lengths that can be picked up by receivers and translated into electronic signals that control displays on a "picture tube".
Most recently, digital signals have replaced analog waves, and of course many people are now receiving the electronic TV digital signals via cable, rather than by air-waves.
TV's, unlike just a radio, need to have a video tube, and an electronic tuner to put "color" pixels onto a screen of some sorts (plasma, or LCD's are more common today, than old picture tubes)
To be true a scientific principle must be theoretically explained and experimentally (and statistically) checked to be correct and repeatable.
All of the components that comprise a television set are developed due to scientific discoveries. TV as a medium, is scientific when showing programs about science.

Principle
Electrodynamic theory.
Manipulation of the radio magnetic spectrum.
about two brainiacs who live next door to a fabulous babe
The scientific principle is friction.... and heat and ultimately the FIRE
Bernoullis principle
people are stupid enough to not believe that a scientific principle supports the facts you know about.
Hovannes Adamian invented the tricolor principle of the color television.
Since it is called "the Heisenberg Uncertainty Principle" it is neither a scientific law nor a theory. It is a principle.
yes
