Q. What is fine structure of spectral lines?
When the spectral line of hydrogen atom is observed by spectrometers having high resolving power it is found that a single line is composed of two or more close components. This is recognized as the fine structure of spectral lines. Bohr's theory couldn't explain the fine structure of spectral lines.
