Homework Help: How it works: television screen

  1. Feb 28, 2012 #1
    1. The problem statement, all variables and given/known data

    Why is the length of time over which a phosphor emits light an imporant factor to consider when designing a television screen?

    2. Relevant equations

    3. The attempt at a solution

    I have gone over the last three chapters in my textbook for the answer. I even drove to the library to try to get some more understanding of it.
