Bohr given a model for hydrogen molecule which is also applicable for some lighter atoms in which a one electron revolves around a stationary nucleus of positive charge Ze (known as hydrogen like atom)
Bohr's model is based on the following postulates.
(i) The electron can revolve only in particular discrete non-radiating orbits, named stationary orbits, for which total angular momentum of the revolving electrons is an integral multiple of
Describe how tunneling takes place When tunnel diode is forward biased, its initial behaviour is similar to that when it's reverse biased. Now, some of the fille
Third Harmonic- Standing Waves on a String There are a variety of patterns that could be generates through vibrations inside slinky, a string, or rope. Each pattern corresponds
Q State Ohm's law. At a steady temperature that the steady current flowing through a conductor is directly proportional to the potential difference between the two ends of the
One scientist wants to put an 100kg experimental package in orbit around the Earth. The cost of deployment depends on the amount of more extra energy it takes to get it into the r
What occures to the normal shift when the thickness of the optical medium is decreased? Write down the expression for equivalent focal length of combination of two thin lenses d
What is electric flux? Write its S.I. units. Using Gauss's theorem, assume an expression for the electric field at a point because of a uniformly charged infinite plane sheet.
BCS theory (J. Bardeen, L.N. Cooper, J.R. Schrieffer; 1957) A theory put forth to describe superconductivity and superfluidity both. This recommend that in the superconducting
The electric utility invoice for a household shows a usage of 1245 kWh during a certain 30-day period. What is the average power consumption during this period?
The Schottky diodes are a semiconductor diode with a low forward voltage drop and a very fast switching action. The voltage drop at forward biases of around 1ma is in the range 0.1
