Question

What is the shortest wavelength in the paschen series?

Answer 1

We have to find the shortest wavelength.

For the shortest wavelength in paschen series.

n₂ = ∞ , n₁ = 3

By the Rydberg equation,

λ min = 9 /1.097 × 10⁷ m

λ min = 8.204 × 10⁻⁷

λ min = 8204 A°

The shortest wavelength in the Paschen spectral line is 8204 A⁰.
