Which has longer wavelength?
kim (jk36442) – EM waves and particles – yeazell – (58005) 3 is inversely proportional to momentum, so twice the momentum means half the wave- length. Thus the slower electron has the longer wavelength. 006 10.0points What is the uncertainty in the speed of a proton if it is desired to locate its position to within an uncertainty of x = 1 . 92 nm ? Planck’s constant is 6 . 63 × 10 34 J · s and the mass of the proton is 1 . 67 × 10 27 kg. Use the Heisenberg uncertainty principle, x p x h 4 π 0 0 - 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 n = 4 n = 3 n = 2 n = 1 Energy (eV) Which of the following photon energies E γ could NOT be found in the emission spectra of this atom after it has been excited to the n = 4 state? Which of the following transitions will pro-

n = 1 n = 2 n = 3 n = 4 The highest-frequency transition is from quantum level 4 to level 1. The lowest- frequency transition is from quantum level 4 to level 3. 009(part1of3)10.0points Consider just four of the energy levels in a certain atom, as shown in the diagram below.
n = 1 n = 2 n = 3 n = 4 How many spectral lines will result from all possible transitions among these levels? Which transition corresponds to the highest- frequency light emitted? Which transition corresponds to the lowest-frequency?
