photoelectric effect properties

The Photoelectric Effect - There are three ways in which electrons eject out of a material. They are (i) Thermionic emission (ii) Field emission (iii) Photo electric emission In all the above cases, energy is given to the material but in different forms. If given in the form of ..

There are three ways in which electrons eject out of a material. They are (i) Thermionic emission (ii) Field emission (iii) Photo electric emission In all the above cases, energy is given to the material but in different forms. If given in the form of heat it is called as Thermionic emission, if in..

Hydrogen bonding has important effect on many physical properties of compounds, described bel..

Association The weak electrostatic interactions of intermolecular hydrogen bonding, causes two or more molecules of a compound to exist as aggregates or associated molecules. This is seen in water molecules, which undergo molecular association. Alcohols and carboxylic acids (RCOOH) als..

If two or more structures can be assigned to a molecule, none of which is capable of describing all the known properties of the compound, then the actual structure is known to be a resonance hybrid or an intermediate of these structures. The various structures written are called res..

The Effects of Oxidation Reactions In Every Day Life - Corrosion :- Many metals are chemically active elements and get easily affected by substances like moisture, air, acids, etc. One must have observed iron articles that are shiny when new, but get coated with a reddish brown powder whe..

Resonance or Mesomeric Effect - If two or more structures can be assigned to a molecule, none of which is capable of describing all the known properties of the compound, then the actual structure is known to be a resonance hybrid or an intermediate of these structures. The vario..

Although a colloidal solution appears to be homogenous because the dispersed particles are too small too be seen, it can be distinguished from a true solution by its ability to scatter light. The scattering of light by colloidal sized particles is called the Tyndall effect. This eff..

Conductors have free electrons. Electrostatic field inside a conductor is zero. At the surface, electrostatic field is normal to the surface at every point. Electrostatic field at the surface of charged conductor is given by ..
