1. The lines observed in H-lamp are parts of Balmer Series. Allthese lines are due to a transition from various higher n value toa common n. What is this common lower n value for all theselines?
0

3
2. The lines on Absorption Atomic Spectra correspond to energiesneeded for electrons to be excited from a lower energy level to ahigher energy level. Assume that the energy needed for an electronin 2p orbital in an O atom to jump to 3s orbital is 3.610-19 J,what is its wavelength of the line atomic spectra in nanometer(nm)?
3. Given: In Atomic Spectra lab, a student obtained his best-fitline equation to be y = 0.29 x + 46.8 when he plotted his Vernierreading on the y-axis and wavelength in nm on the x-axis.
4. The only electron in a hydrogen atom moved from n=2 to n=6.What is the wavelength of photon (in nm) being associated with thistransition? Use whole numbers of nm without any decimal places,such as \"415\", \"1125\".
5.
Which of the following transitions in H will absorb the longestwavelength photon?
n=1 to n=2
n=2 to n=4
n=10 to n=3
n=3 to n=100
6. A student obtained the Rydberg constant to be 2.1710-18 J.What is the % error of the measurement? Answer as percentage andkeep one decimal place.
