Question 1

Calculate the wavelength of the light emitted by a hydrogen atom during a transition of its electron from the n = 4 to the n = 1 principal energy level.  Recall that for hydrogen En = –2.18 × 10–18 J(1/n2)
◦ 6.8 × 10–18 nm
◦ 0.612 nm
◦ 82.6 nm
◦ 97.2 nm
◦ 365 nm

Question 2

Calculate the wavelength, in nanometers, of the light emitted by a hydrogen atom when its electron falls from the n = 7 to the n = 4 principal energy level.  Recall that the energy levels of the H atom are given by
         En = –2.18 × 10–18 J(1/n2)
◦ 9.18 × 10–20 nm
◦ 4.45 × 10–20 nm
◦ 2.16 × 10–6 nm
◦ 2.16 × 103 nm
◦ 1.38 × 1014 nm
