A Cathode–Ray Tube (CRT) is a vacuum tube containing one or more electron guns

Which emit electron beams that are manipulated to display images on a phosphorescent screen.The images may represent electrical waveforms (oscilloscope)

1. Pictures
2. Radar targets

Or other phenomena.A CRT on a television set is commonly called a Picture Tube.CRTs have also been used as memory devices

In which case the screen is not intended to be visible to an observer.The term cathode ray was used to describe electron beams when they were first discovered

Before it was understood that what was emitted from the cathode was a beam of electrons.

Kundt's tube is an experimental acoustical apparatus invented in 1866 by German physicist August Kundt for the measurement of the speed of sound in a gas or a solid rod.The experiment is still taught today due to its ability to demonstrate longitudinal waves in a gas.It is used today only for demonstrating standing waves and acoustical forces.

The Night Tube and London Overground Night Service

Often referred to simply as Night Tube

Is a service pattern on the London Underground (Tube) and London Overground systems which provides through-the-night services on Friday and Saturday nights on the Central

1. Jubilee
2. Northern

Or cold cathode display

Is an electronic device used for displaying numerals or other information using glow discharge.

Pneumatic tubes are systems that propel cylindrical containers through networks of tubes by compressed air or by partial vacuum.They are used for transporting solid objects

As opposed to conventional pipelines which transport fluids.In the late 19th and early 20th centuries

Pneumatic tube networks gained acceptance in offices that needed to transport small

1. Urgent packages
2. Such as :
3. Mail
4. Other paperwork
5. Or money

Over relatively short distances

1. Within a building or
2. At most

Within a city.Some installations became quite complex

But have mostly been superseded.However

They have been further developed in the 21st century in places such as :

To send blood samples and the like to clinical laboratories for analysis.

The Tubes are a San Francisco-based rock band.Their self-titled 1975 debut album included the single White Punks on Dope

While their 1983 single She's a Beauty was a top-10 U.S. hit and its music video was frequently played in the early days of MTV.The band also performed in the 1980 film Xanadu

Singing the rock portion of the cross-genre song Dancin' opposite a big band.

1. A tube
2. squeeze tube

Or collapsible tube is a collapsible package which can be used for viscous liquids such as :

1. Toothpaste
2. Artist's paint
3. Adhesive
4. Caulk

& ointments.Basically

Hollow piece with a round or oval profile

1. Made of plastic
2. Paperboard
3. Aluminum

Or other metal.In general

On one end of the tube body there is a round orifice

Which can be closed by different caps and closures.The orifice can be shaped in many different ways:

Plastic nozzles in various styles and lengths are most typical.The other end is sealed either by welding or by folding.

The Tube map is a schematic transport map of the lines

Stations and services of the London Underground

Known colloquially as the Tube

Hence the map's name.The first schematic Tube map was designed by Harry Beck in 1931.Since then

It has been expanded to include

More of London's public transport systems

The Docklands Light Railway

1. London Overground
2. The Elizabeth line
3. Tramlink

The London Cable Car and Thameslink.

The tube zither is a stringed musical instrument in which a tube functions both as an instrument's neck and its soundbox.As the neck

It holds strings taut and allows them to vibrate.As a soundbox

It modifies the sound and transfers it to the open air.The instruments are among the oldest of chordophones

Being a very early stage in the development of chordophones

And predate some of the oldest chordophones

1. Such as :
2. The Chinese Se

Zithers built on a tube split in half.Most tube zithers are made of bamboo

Played today in Madagascar

Southeast Asia and Taiwan.Tube zithers made from other materials have been found in Europe and the United States

Made from materials such as :

1. A vacuum tube
2. electron tube
3. valve
4. Or tube

Is a device that controls electric current flow in a high vacuum between electrodes to which an electric potential difference has been applied.

Video camera tubes were devices based on the cathode ray tube that were used in television cameras to capture television images

Prior to the introduction of charge-coupled device (CCD) image sensors in the 1980s.Several different types of tubes were in use from the early 1930s

And as late as the 1990s.
