The wavelength of the first line of Lyman series is given by 1 / λ = R [1/1² - 1/2²]. What is the value of λ?
Q1. The wavelength of the first line of Lyman series is given by 1 / λ = R [1/1² - 1/2²]. What is the value of λ?
Answer: 121.6 nm
Explanation: 1 / λ = R [1 - 1/4] = 3R/4, λ = 4 / 3R = 4 / (3 * 1.097 * 10^7) = 121.6 nm.
