H-alpha (Hα) is a specific deep-red visible spectral line in the Balmer series with a wavelength of 656.28 nm in air; it occurs when a hydrogen electron falls from its third to second lowest energy level. H-alpha light is the brightest hydrogen line in the visible spectral range.
What is the first line of Balmer series?
The 3→2 transition depicted here produces H-alpha, the first line of the Balmer series. For hydrogen (Z = 1) this transition results in a photon of wavelength 656 nm (red).
What is limiting line in Balmer series?
Limiting line in the Balmer series has a wavelength of 364.4 nm.
What are limiting lines?
The limiting line is basically when you consider shoving a new electron into the atom and forcing it to land in the destination energy level nf for the particular series... So, we have nf=2 and ni=∞ in the Rydberg equation for hydrogen-like atoms (e.g. He+ , Li2+ , etc):
What is the limiting line of Lyman series?
The Lyman limit is the short-wavelength end of the hydrogen Lyman series, at 91.2 nm (912 Å). It corresponds to the energy required for an electron in the hydrogen ground state to escape from the electric potential barrier that originally confined it, thus creating a hydrogen ion.
Which Colour has the highest wavelength?
Red Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together, they make white light.
