Homework Help: Please help on my Cathode ray tube experiment

  1. Jan 25, 2014 #1
    1. The problem statement, all variables and given/known data
    I am building a CRT for my physics project but have some doubts. I know there will fluorescence effect but my project requires to do an experiment and make observations.

    So how can I relate this experiment so that I have:- 1. Different cases and experiments with the CRT. 2. I am able to make some observations with the above.

    Any variation or anything that helps.


    2. Relevant equations


    3. The attempt at a solution

    Hi modi96! http://img96.imageshack.us/img96/5725/red5e5etimes5e5e45e5e25.gif [Broken]

    You are doing some glassblowing to manufacture your own evacuated thermionic tube?

    Can you demonstrate how the beam can be deflected by both magnetic and electric fields?

    Hi Minn Lwin. :welcome:

    Unfortunately, you are unlikely to get a response from modi because he/she has not logged in to read these forums for over 2 years, so is likely to remain unaware of your enquiry here.

    If you have difficulty in understanding something you are welcome to start your own thread to ask some questions.
