The Paschen series in the hydrogen spectrum corresponds to transitions to the n = 3 state. What is the wavelength of the first line in the Paschen series?
Q1. The Paschen series in the hydrogen spectrum corresponds to transitions to the n = 3 state. What is the wavelength of the first line in the Paschen series?
Answer: 1282 nm
Explanation: Use the Rydberg formula 1 / λ = R * (1 / 3² - 1 / 4²) to find λ = 1875 nm is incorrect, actual value is 1282 nm.
