to get high acceleration for the beam.
A: xray emits from TV, OSCILLOSCOPE and some more instruments due to requirement of hi voltage to see the display
The screen is coated in a thin layer of phosphorous. This glows when bombarded by electrons.
It works on the following principles : (i)thermionic emission (ii)deflection of the electron beam by the electric and magnetic field (iii)fluorescence produced by the electron beam on a fluorescent screen
As with analog ( Dial) watches versus Digital clocks- there are two different types of presentation. The Analog Oscilloscope is more properly called a Cathode Ray oscilloscope as it uses a specialized CRT ( Cathode Ray tube) the Digital creates and displays its graphics in a digital fashion. They do not need a warm-up time as they do not use vacuum tubes. Storage oscilloscopes, which have a time-lapse feature most intriguing and a memory bank, can be and have been made in both the analog and the digital configurations. the German Hameg company marketed both types.

Why is the speed of the electron beam greater than the speed of light in cathode ray oscilloscope.
The most important part of an oscilloscope is the cathode ray tube.
Yes.
