The wavelength of a spectral line in the Lyman series is given by 1 / λ = R * (1 / 1² - 1 / n²). For n = 2, what is 1 / λ?
Q1. The wavelength of a spectral line in the Lyman series is given by 1 / λ = R * (1 / 1² - 1 / n²). For n = 2, what is 1 / λ?
Answer: 3R / 4
Explanation: Substituting n = 2 in the formula, 1 / λ = R * (1 - 1 / 4) = 3R / 4.
