Question

“Bohr’s model failed to account for splitting of line spectra.”

Observe the above sentence, now answer the following questions.

i) Which theory explain splitting of line spectra.

ii) Sommerfeld added how many elliptical orbits to Bohr’s third orbit.​

Answer 1

Answer:

i) Star effect.

ii) Two

Explanation:

i)The Stark effect is the shifting and splitting of spectral lines of atoms and molecules due to the presence of an external electric field. It is the electric-field analogue of the Zeeman effect, where a spectral line is split into several components due to the presence of the magnetic field.

ii) Two elliptical orbits were added by Sommerfeld to Bohr's third orbit. The purpose of adding elliptical orbits was to account for splitting of spectral lines in Hydrogen spectrum.
