What is the wavelength, in nm, of the spectral line resulting from the transition of an electron from n = 3 to n = 2 in a Bohr hydrogen atom? The constant for Balmer's equation is 3.2881 × 10¹⁵ s-1.

The wavelength can be calculated using the Rydberg formula for hydrogen: 1/λ = R_H (1/n1² - 1/n2²), where R_H is the Rydberg constant (1.097 × 10^7 m^-1). For the transition from n=3 to n=2, the wavelength is approximately 656 nm, which is in the visible spectrum (Balmer series).
