Concept introduction:
Bohr proposed that electrons travel in circular orbits around the nucleus. An electron can jump between these orbits by absorbing or emitting a fixed amount of energy. The emission spectrum of atomic hydrogen has been divided into no. of spectral series according to lower energy state. Such as Lyman series, Balmer series, Paschen series and Fund series.
Answer to Problem 99A
The blue-green line in hydrogen atomic emission spectrum is produced when going from the
Explanation of Solution
Lymen series includes lines emitted by transition of electrons from an outer orbit of quantum no.
The Balamer series includes lines that are emitted by the transition from an outer orbit
Other series like Paschen series and Fund series has lines that reside in the Infra Red region of the light spectrum. Now we know that which lines is visible part of light spectrum. So we can look for the blue green lines in Balmer series.
The range of wavelengths in the visible spectrum are the line with a wavelength of
That leaves us with a line at
The blue-green line in hydrogen atomic emission spectrum is produced when going from the
