Compare your calculated hydrogen TOF with the experimental one. How can the discrepancy explained? Select all that applies. Group of answer choices Air resistance can slow down H+ ions Molecules colliding in the Time-of-Flight Imperfections of the electric field in the Time-of-Flight Protons are traveling fast and relativistic effects have been neglected Interaction with surrounding molecules Exact location of the laser focus is not known Some proton have more energy than just the electric potential energy Electron multiplier response time is too long Path traveled by the protons may not be completely straight
