Question: Calculate the wavelength of the photon emitted when a hydrogen <strong>atom</strong> in n=7 undergoes a transition to n=3 (what is the name of this series?). Key equation: hcR = 13.60 eV Step 1: Calculate En=7 and En=3. E7 = -13.60/7 2 = -0.2776 eV E3 = -13.60/3 2 = -1.511 eV
Question: Calculate the wavelength of the photon emitted when a hydrogen <strong>atom</strong> in n=7 undergoes a transition to n=3. Step 1: Calculate En=7 and En=3. E7 = -13.60/49 = -0.2776 eV E3 = -13.60/9 = -1.511 eV Step 2: Calculate ∆E... ∆E = E7 - E3 = (-0.2776) - (-1.511) = 1.233 eV Step 3: Calculate ∆E... ∆E = 1240./λ λ = 1240./ΔE = 1006 nm
