Dimensional formula of Rydberg constant
[L-1]
The constant in 1/λ = R(1/n1² minus 1/n2²) for hydrogen lines. It is one over length.
How to get the dimensional formula of Rydberg constant
- Start from the definition: Rydberg constant = 1 / length.
- Put in the dimension of each part: 1 / [L].
- Add the powers of each base quantity: [L-1].
