Class 11 Chemistry simulations · Structure of Atom

Spectral series of hydrogen

Choose a series and the upper level to see the wavelength of the emitted line.

Open the simulation

What to notice

Only the Balmer series falls in the visible region; Lyman lines are ultraviolet.

Key relation

1/λ = R_H (1/n₁² − 1/n₂²) ; R_H = 109 677 cm⁻¹

Try this

Find the wavelength of the red Balmer line (n₂ = 3).

What you can change

• Series (n₁): 1 to 5
• Upper level n₂: 2 to 8
