    1. The problem statement, all variables and given/known data
    1) Describe and explain what happens to the electron beam on the screen of a teltron tube as the EHT(electrical high tension) voltage increases from 3000V to 3500V.
    2)What is the effect of E field on light waves?

    2. Relevant equations

    3. The attempt at a solution
    1) The beam deflects more as the voltage increases(?? but how much more)
    2)No effect?

    1) What is the direction of the EHT potential difference wrt the direction of the electron beam ? (In other words: what's the function of this EHT ?)

    2) Because ?

    You need to consider what the equations of motion are and write these down.
