Device that uses electrons to produce images on a screen?

A cathode ray tube (CRT) television or computer monitor converts electrical signals into a beam of high-speed electrons that strike a phosphor-coated screen, creating images. The beam scans line by line across the screen to produce the visual display.


What evidence did Thomson have that his glowing beam contained negative particles?

J.J. Thomson discovered that his glowing beam contained negative particles by observing the deflection of the beam in an electric field and measuring the charge-to-mass ratio of the particles. This led to his conclusion that the particles in the beam were negatively charged electrons.


What is the difference between a compound microscope and an electron microscope?

Compound microscopes (also called compound light microscopes) employ light and an array of glass lenses to magnify an object. (This is distinguished from a simple microscope of one lens.) An electron microscope uses a beam of electrons to magnify an object. The lensing system employs electric and magnetic fields and is specialized for applications requiring much higher magnification.

What are the the uses of stopper?

Stoppers are commonly used to seal containers such as bottles or test tubes to prevent spillage or contamination. They are also used in laboratories to control the flow of liquids or gases in experiments. In addition, stoppers can be used as plugs in sinks or drains to block water from flowing.
