Coherence can be classified into two ways: a) temporal coherence: consider a light wave traveling along +X axis. Consider two different points A and B
When a laser beam is emitted from a source, there may be phase difference between the beams at different points that is it may be
A laser beam has following important characteristics: Divergence or directionality: laser is highly directional beam. monochromaticity: laser is monochromatic that is it has single wavelength
The lasers can be classified by various ways, as explained below: a) State of laser medium: According to state of laser medium, we have solid
Coercivity is defined as the value of the magnetising field at which the intensity of magnetisation becomes zero. It is also known as coercive field.
The magnetism remaining in the magnetic material, even when the magnetising field is reduced to zero is called residual magnetism. The power of retaining this
Soft magnetic materials have low retentivity and low coercivity. These are those materials which have high initial permeability, low hysterisis loss and large magnetic induction.
Name: Central Scientific Instruments Organisation (CSIO) Services: CSIO is one of the premier national laboratory of India dedicated to research, design and development of scientific
Ferrimagnetic materials commonly known as ferrites, can be generally represented by chemical formula XOFe2O3, where X stands for Mn, Co, Ni, Cu, Mg, Zn, Cd
Ferrites have following applications: Ferrites have importance in engineering and technology because they possess spontaneous magnetic moment below the Curie temperature just as iron, cobalt,
