Final answer:
The question pertains to the Hydrogen Emission Spectrum in physics. The electron in question moved to the n=2 energy level, emitting a light wavelength of 486.1 nm. Using the Rydberg formula, it was likely at the n=4 energy level originally.
Step-by-step explanation:
The question you asked relates to the hydrogen emission spectrum, a key concept in quantum physics. The electron you mentioned changes its energy level from a higher to a lower state, in this case, to the n=2 level. The excess energy results in the emission of light, with a wavelength related to the difference in energy levels. We use the Rydberg formula to calculate these energy levels:
Rydberg Formula: 1/λ = R*(1/n12 - 1/n22) where R is the Rydberg constant ≈ 1.097 x 107 m-1. From the formula, solve for n1, where n2 = 2 and λ = 486.1 nm.
Performing the calculations, the electron likely originated in the n=4 energy level.
