Cathode rays consist of electrons. In order to keep the electrons in a cathode ray from scattering due to collisions with air molecules, a CRT needs to be sufficiently evacuated of air.
Yes, there are magnets in CRTs
LCDs require less power than CRTs, they also do not flicker.
Either an electrostatic field or a magnetic field. Each type is used in cathode ray tubes: generally, electrostatic in oscilloscopes, magnetic in television and computer CRTs.
yes
Handle monitors and CRTs with care. Extremely high voltage can be stored in monitors and CRTs, even after being disconnected from a power source. CRTs contain glass, metal, plastics, lead, barium, and rare earth metals. According to the U.S. Environmental Protection Agency (EPA), CRTs may contain approximately 4 lbs (1.8 kg) of lead. Monitors must be disposed of in compliance with environmental regulations.
CRTs use an electron beam.
crts (abbreviation for cathode ray tubes)
Early types of monitors were CRTs (cathode ray tube).
While there are high-resolution CRTs, they don't come in widescreen, so no.
Assuming it's a CRT, it is actually a vacuum in the tube. That is because CRTs (normal, ISM (invar shadow mask) or Aperture grill (most advanced of CRT)) work by making electricity go inside a tube and hit a subpixel. That causes it to create visible light somehow, and electricity travels best in a vacuum; conductive gas will screw up the picture because it will throw off the beam of electricity. and hit an unintended spot. To make a long story short, there is no gas; just a vacuum.
Yes. Cathode ray tubes, (CRTs) will continue to exist, but will increasingly become obsolete.
Dot_pitchdefines the maximum resolution of the display, assuming delta-gun CRTs. In these, as the scanned resolution approaches the dot pitch resolution, Moiré appears, as the detail being displayed is finer than what the shadow mask can render.Answers.comAperture grille monitors do not suffer from vertical moiré, however, because their phosphor stripes have no vertical detail. In smaller CRTs, these strips maintain position by themselves, but larger aperture grille CRTs require one or two crosswise (horizontal) support strips.Answers.com
