प्रश्न
What is the experimental evidence in support of the idea that electronic energies in an atom are quantized?
उत्तर
The line spectrum associated with any element possesses lines corresponding to specific wavelengths and these lines are obtained as a result of electronic transitions between the energy levels. Hence, the electrons in these levels have fixed energy i.e., quantized values.
