here is the addition information! thank you!
1. Using the calibration graph and the scale readings for hydrogen, determine the wavelengths for hydrogen emission; enter the results on your data sheet. 2. The four hydrogen lines correspond to the 32,42,52, and 62 transitions. Assign a transition to each wavelength and enter the results on your data sheet. Hint: The lowest wavelength, 410nm, corresponds to the highest-energy transition. The 32 transition emits the least energy. 3. Determine the Rydberg constant from the data. Since for n=2 : 1=RH(ni21nh21)1=22RHRH(nb21)1=RH(nb21)+4RH Equation 1 which is of the form y=mx+b That is, Equation 2 is of the form of a straight line; hence the Rydberg constant is the negative of the slope. Plot y=1/ vs. x=1b2 (in Excel or Google Sheets), then determine the slope m=RH. Be sure to label the axes of the graph. As a check, compare this value of RH with the y-intercept, which should equal RH/4. To make it easy, set up a table (next page) for the data. Use meters for wavelength; the units of RH will be meter 1. Show your calculations in the space below: 4. Calculate the change in energy for each transition, nb=3,4,5,6 and nc=2. Show your work and give the results in units of joules. E=bc=bcRH(n21nh21)Equation332:E=42:E=52:E=62:E= 5. Derive Equation 3 from Equation 1: 6. Determine the ionization energy for the hydrogen atom. The ionization energy is the energy necessary to take an clectron from its most stable state ( n=1 for hydrogen), to a state infinitely far from the nucleus. Use Equation 3 to make the calculation.
