MVP — interactive sketch; a fuller lab is coming later.

CRT / oscilloscope tube

Acceleration qU₁ = ½mv₀²; deflection y₁ = U₂L²/(4dU₁); screen spot Y = U₂L(L+2L₂)/(4dU₁), independent of charge and mass.

CRT / oscilloscope tube

CRT: electron beam accelerated then deflected to hit the screen. This “CRT / oscilloscope tube” page is an MVP interactive sketch — formulas, controls, and live readouts in the browser; a fuller bench may follow.

CRT: electron beam accelerated then deflected to hit the screen.

Key formulas

  • qU_1=\tfrac12 mv_0^2
  • y_1=\frac{U_2L^2}{4dU_1}
  • Y\propto U_2

How to use

  1. Adjust parameters in the left panel.
  2. Use play / pause and speed controls.
  3. Match right-side readouts to the formulas.
  4. Reset to return to the initial state.

Applications

  • CRT / oscilloscope tube: CRT: electron beam accelerated then deflected to hit the screen.
  • Classroom focus: deflection y₁ = U₂L²/(4dU₁).

FAQ

What does MVP mean on this page?

An interactive sketch with formulas and parameters. Polished Ready labs are the full bench experience.

What does the “CRT / oscilloscope tube” lab practice?

Tune parameters and match readouts to the “CRT / oscilloscope tube” relations — useful for prep and demos.

Self-study or classroom?

Both — tune alone, or project “what if…?” demos in class.

Readouts don’t match the formula?

Check units and ranges, then substitute step-by-step from the formula panel.
