The wavelength of a spectral line in the hydrogen spectrum is given by 1 / λ = R * (1 / 2² - 1 / n²). What is the value of n for the third line in the Balmer series?
Q1. The wavelength of a spectral line in the hydrogen spectrum is given by 1 / λ = R * (1 / 2² - 1 / n²). What is the value of n for the third line in the Balmer series?
Answer: 5
Explanation: The third line in the Balmer series corresponds to the transition from n = 5 to n = 2.
