1. The problem statement, all variables and given/known data A beam of electrons is hitting a block of metal with current A. What is the frequency they are hitting the block? 2. Relevant equations i=q/t 3. The attempt at a solution i=q/t => 1/t=i/q. So then 1/t=A/e, where e is the elementary charge. This may in fact be right. Our prof gave it to us as a question to think about and I want to know what everyone else is thinking.
