Answer #1

Part B:

Absorption will take place when electron moves from

1) 0 eV to 3.73 eV

2) 0 eV to 5.58 eV

3) 3.73 eV to 5.58 eV

So wavelength corresponding to the absorption for 0 eV to 3.73 eV = 3330 Å

Wavelength corresponding to the absorption for 0 eV to 5.58 eV = 2226 Å

Wavelength corresponding to the absorption for 3.73 eV to 5.58 eV = 6715 Å

So ascending order = 2226 Å, 3330 Å, 6715 Å

One series of lines in the hydrogen spectrum is caused by emission of energy accompanying the fall of an electron from outer shells to the fourth shell. The lines can be calculated using the Balmer-Rydberg equation: 1λ=R∞[1m2−1n2] where m=4, R∞ = 1.097×10−2nm−1, and nis an integer greater than 4. Part A Calculate the wavelengths in nanometers of the first two lines in the series. Express your answers using four significant figures separated by a comma. Part B Calculate the energies...
