Who invented the first test tube?
John Flamsteed invented the first test tube.
Who invented the electron?
Nobody "invented" the electron cloud. The concept was discovered by Werner Heisenberg in 1926.
Is cathode ray tube and electron tube same?
Yes they are the same. A cathode ray tube (CRT) uses an electron gun to "shoot" electrons from the cathode to specific positions on the anode of the CRT.
What is the positive electrode of an electron tube?
anode

When was the scanning electron microscope invented?
The scanning electron microscope was invented in the 1960s. The first commercial scanning electron microscope was introduced in 1965 by Cambridge Instruments.
What is Electron tube?
An electron tube, also known as a vacuum tube, is a device that controls the flow of electric current through a vacuum between electrodes. Invented in the early 20th century, it was pivotal in the development of early electronics, serving functions such as amplification, rectification, and switching. Electron tubes were widely used in radios, televisions, and early computers before the advent of solid-state devices like transistors, which are now more common. Despite this, electron tubes are still utilized in certain applications, such as high-power radio frequency transmitters and audio amplifiers, due to their unique characteristics.
What does tube mean?
an electron tube containing a near-vacuum that allows the free passage of electric current.
Where was the Electron Microscope invented?
Germany
How a tube light formed?
tube light us formed by sum inerts gasses like neon because they do not react with electron and the friction between electron and neon produced light.
