Question

How does a certain frequency of line occur in the hydrogen spectrum?

Answer 1

Answer: Your welcome!

Step-by-step explanation:

The frequency of a line in the hydrogen spectrum is determined by the difference in energy between two energy levels in the hydrogen atom. The energy levels are determined by the electron's angular momentum and can be expressed as the quantum number n. The energy of the lines is then determined by the difference between two energy levels (n1 and n2) and is given by the equation ΔE = hc/λ = (R/n2^2) - (R/n1^2), where R is the Rydberg constant and h is Planck's constant. The frequency of the line is then determined by the equation ν = ΔE/h.

Answer 2

Answer: Though a hydrogen atom has only one electron, it contains a large number of shells, so when this single electron jumps from one shell to another, a photon is emitted, and the energy difference of the shells causes different wavelengths to be released... hence, mono-electronic hydrogen has many spectral lines.
