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

AI Thread Summary
The discussion focuses on the factors influencing electron beam deflection in a cathode ray oscilloscope, particularly thermionic emission. Key factors identified include the size of the deflecting plates, the potential difference (P.D.) across them, and the length of the plates. The potential difference is crucial as it directly affects the electric field strength, which influences the beam's deflection. The size and length of the plates may have less impact on deflection compared to the P.D. Understanding these factors is essential for grasping the principles of electron beam manipulation in oscilloscopes.

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.

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Struggle to understand the concept of the question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
