What Factors Affect Electron Beam Deflection in a Cathode Ray Oscilloscope?

Click For Summary
SUMMARY

The discussion focuses on the factors affecting electron beam deflection in a cathode ray oscilloscope (CRO), specifically addressing thermionic emission. Key factors identified include the size of the deflecting plates, the potential difference (P.D) across the plates, and the length of the plates. The participants debate the relevance of these factors, with some asserting that the first three do not significantly influence electron deflection. Understanding these elements is crucial for optimizing CRO performance.

PREREQUISITES
  • Understanding of thermionic emission principles

Homework Statement



This question is related to thermionic emmision in a cathode ray oscilloscope. I don't understand what factors affect the amount of deflection of the beam of electrons.
1.The size of the plates
2.The P.D accros the deflecting plates.
3.The length of the plates
4.Any other factors
I would very much appreciate if reasons to the factors are also provided...ie why does (some) particular factor affects the amount of deflection.

i don't think the first 3 factors have any role to play in deflecting electrons.
