Calculate the wavelength, in nanometers, for the colored line that appears in the spectrum of the hydrogen atom corresponding to an n=4 to n= 2 electronic transmission. The hydrogen atom emits visible light at the following wavelengths (given in nanometers with corresponding colors): 410 (violet), 434 (blue), 486 (green), and 656 (red). Part 2: Draw a simple energy level diagram for the hydrogen atom, and illustrate with arrows the transitions that give rise to VISIBLE light emissions.

Question
Part 1: Calculate the wavelength, in nanometers, for the colored line that appears in the spectrum of the hydrogen atom corresponding to an n=4 to n= 2 electronic transmission. The hydrogen atom emits visible light at the following wavelengths (given in nanometers with corresponding colors): 410 (violet), 434 (blue), 486 (green), and 656 (red).
Part 2: Draw a simple energy level diagram for the hydrogen atom, and illustrate with arrows the transitions that give rise to VISIBLE light emissions.
Expert Solution
Step 1
Wavelength can be calculated using the equation:
R = Rydberg constant = 109677 cm-1
n1 = 4
n2 = 2
= 2043750 m-1
= 2.04 * 106 m-1
= 490 * 10-9 m
= 490 nm
Wavelength = 490 nm
