introduction to quantum mechanics experiments

Wave nature of material objects In 1924, de Broglie's suggested that all material objects including an electron have a dual character; they behave as particles as well as waves. The wavelength associated with a particle of mass 'm', moving with velocity 'v' is given by de Broglie's relation as: ..

Breathing Mechanism - The physical movements associated with the gaseous exchange are called breathing. The various structures that are involved in the breathing mechanism are the respiratory passage, the lungs, the outer and inner intercostal muscles, the diaphragm and the musc..

We have seen in the previous lesson that a current carrying conductor when kept in a magnetic field experiences forces and torques. Is reverse phenomenon possible? If we rotate the coil in a magnetic field, will current flow in the coil without we passing it? The answer is yes. Current ca..

Viscosity - When two solid surfaces slide over each other, a frictional force acts between them that opposes the relative motion of the bodies. Similarly, when a layer of a liquid slips on another layer the two exert a tangential force on another. This opposes their motion. The property of a liquid..

Quantum Theory of Covalent Bond - Although the Lewis structures give an idea of the valence electrons around the atom, in reality it does not precisely locate the position of the electrons in the chemical bond. The behaviour of electrons in molecules and compounds is made by the valence b..

Mechanism of Electrolysis - The process of electrolysis is exactly opposite to one that takes place in a voltaic cell. A voltaic cell or a battery uses its chemical energy to produce electrical energy. While in electrolysis, electrical energy is used to bring about a chemical change. Hump..

The process of electrolysis is exactly opposite to one that takes place in a voltaic cell. A voltaic cell or a battery uses its chemical energy to produce electrical energy. While in electrolysis, electrical energy is used to bring about a chemical change. Humphrey Davy (1807) showed this in ..

Electric bell suspended inside an airtight glass bell jar An electric bell is suspended inside an airtight glass bell jar connected with a vacuum pump. As the electric bell circuit is completed, the sound is heard. Now if the air is slowly removed from the bell jar by using a vacuum pump, the i..
