Homework Help: Year 12 EEI - Cathode Ray Tube

  1. Jul 11, 2015 #1
    For my year 12 physics EEI (extended experimental investigation) i need to develop some sort of experiment with variables i can change to retrieve data from. I have a basic cathode ray tube from a few months ago much like the one in this video: . Does anyone have any idea of what variables i could change with this experiment? (Sorry for my english. it's my second language)

    Thank you

    Welcome to the PF.

    You can change the anode voltage while applying different magnitudes of orthogonal B-fields across the neck of the CRT...

    BTW, what accelerating voltage are you planning on using? That bottle looks to be missing any X-ray shielding...
