This new technology for the detection of tumors will save thousands of lives.
CRT and plasma TVs emit x-rays, which can be hazardous.
Substantially lower.
There is no reason to upconvert the signal from a game console. While TV is shot in a certain format, transmitted in another, and displayed in yet another. A game is rendered live and displayed based on the detected TV.
The highest ever detected on the earth's surface is the EM radiation emitted from the radio transmitters on top of the Petronas Twin Towers in Kuala Lumpur and from the TV transmitters on the Willis (Sears) Tower in Chicago. (Air-to-ground communication, transponder, and radar signals emitted from commercial aircraft in flight are judged in a different category.)
In a literal sense no, but they have been detected experimentally. The fact that your television works is proof enough that electrons exist, since an electron is required to strike a screen in order to produce an image.
The gun for the original Duck Hunt used a light sensor. This detected the colors on the screen, I think.
All flat screen televisions are computer based. Although they don't have the same emmissions as CRT televisions, signals can probably be detected that are similar to those emitted by other computing equipment. The design of modern conusmer equipment sets out to minimise the emissions and generally, they will be at a level that cannot be detected in normal situations. The signals emitted are also reduced by distance and by objects so it is very unlikely that any noticeable effects will be seen more than a few inches away. The only likely interference that comes to mind is the use of a radio or television Ariel mounted very close to the television - too close and there may be problems with reception.
the television has a switch that makes possible for it to light on an off, the remote control has a malty sensor that allow sensory waves to be detected in an immediate effect when pressing some of the buttons on the remote control, co ordination is carried by eclectic waves that allow stimuli as electrons pass through conductors allowing a electric flow of current.
If a possible tornado is seen by spotters or detected by radar a tornado warning is issued. The public is then informed of the warning via special TV and radio announcements, as well as through the internet. Some towns sound sirens that warn of a coming tornado.
