The Rydberg equation can be used to calculate the change in energy duting a transition of an electron in a hydrogen atom. The Balmer series k a set of transitions for H-atom where n_final = 2. Calculate the change in energy to three sig tigs (in j) of one transition in the Balmer series for which \( n \) initial \( =4 \). \[ \Delta E=R_{n}\left(\frac{1}{n^{2}}-\frac{1}{n^{2}}\right) \] The Rycberg constant \( \mathrm{RH}=2.18 \times 10^{-18} \mathrm{j} \) Note; to enter a number with unit in scientific notation, enter something like \( 6.02 E 23 \) atoms or \( 1.00 \mathrm{E}-9 \mathrm{~m} \). \( 4.09 \mathrm{E}-19] \) QUESTION 2 True or false: In the previous question, the electron gains energy: True False QUESTION 3 True or false: During the transition that occurs in question 1, a photon is being emitted. True False QUESTION 4 True of false: in question t, the energy of the photon is positive. Hint: consider whether a photon can ever have a negative enerlo. True False Four transtions in the Balmer series are expected to be observed in the hydrogen emission spectrum during the lab though the volet color can be harder to see, and will be ignored in lab). Look up a rainbow spectrum to help you match the four colors to their corresponding wavelengths, A. \( v \) fied A. \( 656 \mathrm{~nm} \) B. \( \sim \) Blueish-green B. \( 486 \mathrm{~nm} \) D. Blue: C. \( 410 \mathrm{~nm} \) Volet. D. \( 434 \mathrm{~nm} \) QUESTION 6 An unknown gas spectrumis measured using the setup described in the intro, One emission line is measured to appear at a distances \( =13.7 \mathrm{~cm} \) to the side from the discharge tube; the distance between discharge tube and diffraction grating is \( x=50.0 \mathrm{~cm} \) (see Figure 2). First, calculate the corresponding wavelength to three sig figs fin \( \mathrm{cm}) \), and then, convert this wavelength to nm. Report the wavelength in nm. \( 569.8 \mathrm{~nm} \) QUESTION 7 Which of the foliomng are reawonable safety concerns for Experiment 8 ? Check any that apply to this particular expeniment only. Consult with the procedure to guide your answer. Forgetting to clamp the Buchiner funnel to a ring stand.
