Calculate Lyman, Balmer, and Paschen Spectral Intervals

[b0094]

Homework Statement

Calculate the spectral interval (λmax, λmin, and Δλ) in which all the lines of the Lyman, Balmer, and Pashcen series (excluding their continuous parts) of the H-atom are found.

Homework Equations

Here is where I am confused.. do I use the Balmer's formula for H?

frequency = [1/4 - 1/n^2] * 3.29*10^(15)s^-1

The Attempt at a Solution

The problem is.. I don't know what energy levels these series correspond to? Is this something I am just supposed to memorize??

 

[rl.bhat]

For Lyman series, transition from n = 2 to n = 1 for λ_max and n= ∞ to n = 1 for λ_min.
Similarly for the other series.

Is the equation I provided correct in this case??
