the_grim_reaper:
Really sorry guys but I still don't get the pin and cylinder thing. You keep the cylinder on the ruler and insert the pin in the gap between them or what????? Please elaborate!!!
Plus why is it necessary to use a DC voltage between the cathode and anode to create cathode rays in a vaccum?????

You place (stick) the pin horizontally, coinciding the mark on the ruler .. u place the cylinder over the pin .. u want me to show u a drawing ??
If u use a.c u wont get a steady ray .. ur cathode and anode would constantly be changing ..
