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.

Yes.
Rs 25,000/-which is a cheap cost
period are measued in oscilloscope by using or calculating time division
The cathode ray oscilloscope was invented by Karl Ferdinand Braun in 1897. It is a widely used electronic test instrument that displays electrical waveforms in real-time.
A German man named Karl Ferdinand Braun
The horizontal and vertical amplifier in the cathode-ray oscilloscope are deflection plates. The horizontal amplifier causes the beam to be deflected horizontally at a rate that is uniform. The vertical amplifier causes the beam to deflect vertically.
