Question 1

If the de Broglie wavelength of an electron is 2.4 μm, what is the speed of the electron?
◦ 2.5 × 105 m/s
◦ 8.3 × 106 m/s
◦ 3.0 × 102 m/s
◦ 1.7 × 103 m/s

Question 2

The figure shows part of the energy level diagram of a certain atom.  The energy spacing between levels 1 and 2 is twice that between 2 and 3. If an electron makes a transition from level 3 to level 2, the radiation of wavelength λ is emitted. What possible radiation wavelengths might be produced by other transitions between the three energy levels?



◦ only λ/2
◦ only 2λ
◦ both 2λ and 3λ
◦ both λ/2 and λ/3
