The Rydberg constant R is given by R = 1.097 * 10^7 m^-1. What is the wavelength of the second line in the Balmer series?
Q1. The Rydberg constant R is given by R = 1.097 * 10^7 m^-1. What is the wavelength of the second line in the Balmer series?
Answer: 486 nm
Explanation: Use the Rydberg formula 1 / λ = R * (1 / 2² - 1 / 4²) to find λ = 486 nm.
