1. The problem statement, all variables and given/known data In a television, an electron is accelerated through a potential difference of 30,000 V. What is the minimum wavelength produced. 2. Relevant equations E = qv E = hf 3. The attempt at a solution I figured that we should first find total energy. E = qv => E = (1 x 10^-16)(30,000) = 4.8 x 10^-15 Then I can manipulate the equation E = hf into E = hc/(lambda) to find the wavelength. I'm not sure if solving this equation will yield the minimum wavelength or the maximum wavelength. What is the case and why?
