Hydrogen Line Spectra
Hydrogen Line spectra – Bohr’s Model Approach According to the third postulate of Bohr’s Model, whenever an electron jumps from higher energy level (orbit) of a Hydrogen atom to one of its lower energy level, an electromagnetic wave (em wave) emits. The energy of em wave is equal to the energy difference between the two…
