sQuestion Completion Status QUESTION 6 of the emission spectrum of a one-electron atomic species is shown below. The highest energy series is shown on the right, and there many more series at lower wavenumbers, which are not shown. The series in the middle starts at 243860.7015 cm1 and terminates at 438949.2627 cm1. What is the wavenumber of the peak marked with an asterisk? Enter only the numerical portion of your answer, to tw decimal places, in the space provided; do not enter the units Right 420,000 620,000 820,000 1.020,000 1.220,000 1420,000 1,620,000 Transition Wavenumber

i have no idea how to start this question. Please help!!! :(

this is the only given information.

Answer 1

The answer can be predicted as the asterisk line lie at the center of the marks 220000 and 420000. Since difference between these is 200000 and half of it is 100000. So, answer is 320000.
