WebErnest Zinck. 7 years ago. The Balmer-Rydberg equation or, more simply, the Rydberg equation is the equation used in the video. 1/λ = R (1/i² -1/j²) It is usually written as. 1/λ = R (1/n₁² -1/n₂²), where n₁ < n₂. For the Balmer series of lines ( the visible lines in the hydrogen spectrum), n₁ = 2.
