If Bohr’s quantisation postulate (angular momentum = nh/2pi) is a basic law of nature, it should be equally valid for the case of planetary motion also. Why then do we never speak of quantisation of orbits of planets around the sun? |

Answer» Solution :The angular momentum associated with planetory MOTION is largely relative to the value of H. For example the angular momentum of the Earth in its orbit is of the order of `10^(70)` h. According to acceptance of Bohr quantization, this leads to a very high value of quantum levels N of the order of `10^(70)` For large values of n, successive energies and angular momentum are relatively very small. HENCE, quantum levels for PLANETARY motion are considered continuous |
