Question

The frequency of a coloured line in hydrogen

spectrum is found to be 6.18 × 1014 Hz. The

designation of the spectral line is

1) H alpha 2) H beeta3) H gama 4) H​

Answer 1

Answer:

Explanation:

The correct answer is - When they get ionized.

H-alpha (Hα) emission is defined as the red visible spectral line that is created by a H₂ atom when an electron falls to the second lowest energy level from the third lowest.

For atomic Hydrogen, the red H-alpha spectral line of the Balmer series conspicuously occurs when there is a transition from the n = 3 shell to the n = 2 shell. In such a case, the H₂ atom will emit an H-alpha light and the H-alpha line will be formed where the hydrogen atom is being ionized.

Answer 2

Answer:

The frequency of a coloured line in hydrogen

spectrum is found to be 6.18 × 1014 Hz. The

designation of the spectral line is 1.H alpha.

Explanation:

• H alpha is a specific spectral line in the Balmer series. It falls in the deep red coloured visible spectral region.
• This H alpha transition is likely to occur when an electron falls from the third transition state to the second transition state. (lowest energy state).
• Spectral series is a series of wavelengths arranged in an array released from the energised atoms.
• The spectral series of hydrogen atom include Lyman series, Balmer series,Paschen series Bracket series and Pfund series. A new series called Humphreys series has recently been discovered.
• The spectral lines of lyman series falls in ultraviolet region, Balmer series falls in the Visible region, paschen series, Bracket series, Pfund series lies in the Infrared region.
