Derive an expression for critical velocity of a satellite revolving around the earth in a circular orbit. On the basis of Bohr's postulates derive an expression for orbital velocity of an electron in n th stationary orbit of hydrogen atom.

Bohr's model of the atom was valuable in demonstrating how electrons were capable of absorbing and releasing energy, and how atomic emission spectra were created. However, the model did not really explain why electrons should exist only in fixed circular orbits, rather than being able to exist in a limitless number of orbits with different energies. In order to explain why atomic energy states are quantized, scientists had to rethink their views of the nature of the electron and its movement. Planck's investigation of the emission spectra of hot objects and the subsequent studies into the photoelectric effect had proven that light was capable of behaving both as a wave and as a particle. It seemed reasonable to wonder if electrons could also have a dual wave-particle nature. In , French scientist Louis de Broglie derived an equation that described the wave nature of any particle.

Velocity of an electron in nth orbit

The model has a special place in the history of physics because it introduced an early quantum theory, which brought about new developments in scientific thought and later culminated in the development of quantum mechanics. When we use a prism to analyze white light coming from the sun, several dark lines in the solar spectrum are observed Figure 6. Solar absorption lines are called Fraunhofer lines after Joseph von Fraunhofer , who accurately measured their wavelengths. During —, Gustav Kirchhoff and Robert Bunsen discovered that for the various chemical elements, the line emission spectrum of an element exactly matches its line absorption spectrum. The difference between the absorption spectrum and the emission spectrum is explained in Figure 6. An absorption spectrum is observed when light passes through a gas. This spectrum appears as black lines that occur only at certain wavelengths on the background of the continuous spectrum of white light Figure 6.
