In an oscilloscope, the cathode emits the electrons which are accelerated by the anodes. Explain the kind of voltages to be applied to the horizontal and vertical plates so that images formed on the deflecting screen are
(1) horizontal line (2) vertical line
A horizontal line can be formed on the screen if the electron beam is deflected horizontally. To move it horizontally, over the whole screen, an alternating voltage is required.
A vertical line can be formed on the screen, if the electron beam is deflected vertically. To move it vertically over the whole screen, an alternating voltage, is required.
