A vacuum is needed in the deflection tube to prevent the interference of air molecules with the movement of electrons. Air molecules can scatter and absorb electrons, affecting the accuracy of the electron beam's deflection. By removing air and creating a vacuum, the path of the electrons remains unobstructed, allowing for precise control and movement within the tube.

Who invented the vaccum tube?
The vacuum tube was invented by Thomas Edison in the late 19th century. However, it was not until Lee de Forest's modification in 1906 that the vacuum tube became an essential component in early electronics.
What is the solution to a cathode ray tube physics problem involving electron acceleration and deflection?
The solution to a cathode ray tube physics problem involving electron acceleration and deflection is to apply the principles of electromagnetism and the laws of motion to calculate the trajectory of the electrons as they are accelerated and deflected by electric and magnetic fields within the tube. By solving the relevant equations, one can determine the path of the electrons and predict their behavior within the cathode ray tube.
What replaced the vacuum tube?
The transistor replaced the vacuum tube as the primary component in electronic devices, offering smaller size, lower power consumption, and higher reliability. This transition marked the beginning of the semiconductor era in electronics.
When was the vacuum tube invented?
The vacuum tube was invented in 1904 by John Ambrose Fleming, an English engineer.
What did j.j Thomson experiment with?
J.J. Thomson experimented with cathode rays in a vacuum tube, which led to the discovery of the electron in 1897. By measuring the charge-to-mass ratio of electrons, he determined that they were a fundamental particle and were present in all atoms.
Why deflection is necessary in cathode ray tube?
It is not necessary in a cathode ray tube, it is a side effect and is needed in the calculations to ensure that there are no errors.
What computer component did the transistor replace?
the vacuum tube
What is the stream of particles originating from a cathode in a vacuum tube?
Not sure of the question, but *electrons flow from cathode to plate in a CRT. A deflection coil guides the electron beam to various areas of the screen. Some CRTs use electrostatic deflection, where the beam is deflected by four grids that steer the beam.
What are the elements of a vacuum tube?
A vacuum tube is simply a tube with no oxygen nor carbon dioxide in it (aka no air).
What is in a vacuum tube?
Millman's theorem
What is deflection in picture tube?
Stay with this guys, you're hlepnig a lot of people.
Where was vacuum tube was made?
who made the vacuum tubes
How many KB is a vacuum tube?
Kilobytes and vacuum tubes are not in the same category. At best, a twin triode vacuum tube is a single flip-flop and can hold 1 bit of information, making a vacuum tube about 0.000122 of a kilobyte.
What causes a slanted tv picture?
If the deflection yoke is rotated it can cause a slanted TV picture. The deflection yoke is located on the tube neck inside the TV.
What is the unit of deflection sensitivity of cro?
The unit of deflection sensitivity of a Cathode Ray Oscilloscope (CRO) is volts per division on the vertical axis of the screen. It represents how much voltage change is needed to move the electron beam by one division vertically on the screen.
What does vacuum tube mean?
an electron tube containing a near-vacuum that allows the free passage of electric current.
What are example of vacuum tube?
cellphone
