Physics Lab Report

In this lab our throng was to find how the buckle of the electron beam varies when passing through an electric field obligation to the velocity of the electron beam. It seemed fairly conf victimisation at first, keep mum as we started working on the equation, the ideas involved were easily understandable. The b arely confusing part was defining the equation that we should use to designate the results. Equipment: 1 Cathode Ray Tube (with deflection plates and a graph on the end) 1 exponent tote up sextuple connectors          Our group hooked up the cathode Ray Tube to the power supply with the connectors, and curveed it on. The first time we did this it didnt work, so we checkered with the TA and found that we were supplying too many volts to the CRT. We were using 500V or else of 250V. We fixed this problem and a special K scatter appeared on the screen at the end of the CRT. Because gravity and magnetic handle in the room were acting on the CRT, we had to turn it about to find a plane in which the green flock lined up in the center of the graph. We enforce this as our point of origin. We then proceeded to measure the distance the dot traveled resulting from several different potentialitys applied to the deflection plates. The deflection plates used the voltage to make the electrons change their path.

With more voltage the electrons were deflected a farther distance from origin.         I was unable to happen up with an equation that would produce the amount of total deflection. We worked on it for a while and our attempt s proved inadequate. Our TA gave us the equ! ation: tot Deflection = E L (D + L/2) 2 Vacc         These are your readings from the chart on the end of the CRT: Y          case (mm) ...
