The wavelength of the first line of the Lyman series is 1216 Å. What is the wavelength of the second line?
Q1. The wavelength of the first line of the Lyman series is 1216 Å. What is the wavelength of the second line?
Answer: 1026 Å
Explanation: For Lyman series, 1/λ = R(1/1² - 1/n²). For n = 3, 1/λ = R(1 - 1/9), giving λ = 1026 Å.
