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. Thanks. 2. Relevant equations None. 3. The attempt at a solution None.
