An electron in a hydrogen atom makes a transition from the n = 3 to the n = 1 energy state. Determine the wavelength of the emitted photon (in nm).
A) 1006
B) 209
C) 306
D) 103
E) 821

The wavelength of the emitted photon 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 x 10^7 m^-1), n1 = 1, and n2 = 3. Solving this gives λ ≈ 103 nm.
