Displacement

Added on 16 April 2009

The displacement of a particle is defined as the change in position of the particle in a particular direction and is given by a vector drawn from the particle’s initial position to its final position.
The length of the actual path between the initial and final positions of the particle is called the distance covered by it.Suppose that a particle is moving from point A to point B….

Laurent’s Half-Shade Polarimeter

Added on 15 April 2009

It is used for the measurement of the angle of rotation of optically active substance in solution. That is, angle through which the plane of the polarized light is rotated on passing through a specific length of solution of known concentration.
The experimental arrangement is shown if figure, S is source of monochromatic light placed at the focus of convex lens L. The beam, rendered parallel by lens L, falls on called polarizer P. After passing through polarizer P the light….

Dielectric

Added on 10 April 2009

A dielectric is a material which contains no free electrons, so that no current can flow through them. As a result, the electrical conductivity of a dielectric is poor and for an ideal dielectric it comes out to be zero.
According to band theory of solids, a dielectric is a material in which the energy band gap between valence and conduction band is more 3 eV. Glass, plastic, mica etc. are examples of dielectrics. When a polar or non-polar molecule is placed in an external electric field….
