This video explains the concept of the Bohr model as proposed by Neils Bohr to describe the absorption and emission of light from the hydrogen atom. Bohr won the Nobel prize in physics in 1922 for this.
Also included is a worked example of how to use an energy level diagram to calculate the wavelength of light emitted from a hydrogen atom when its electron transitions from a higher energy level to a lower energy level.
The most common energy level transitions are (1) the Lyman series in which electrons transition to the ground state (n = 1). This series emits light in the ultraviolet; (2) the Balmer series in which electrons transition to first excited state (n = 2). This series emits light in the visible portion of the spectrum; (3) the Paschen series in which electrons transition to second excited state (n = 3). This series emits light in the infrared portion of the spectrum.
