Conventional and Non Conventional Sources of Energy Main Sources of Energy: The sources of energy are of following types: Conventional Sources of Energy: These sources of energy are also called non renewable sources. These sources of energy are in limited quantity except hydro-electric power. (a) Coal and Lignite: Coal is the major Source Of Energy. Coal … Read more
Conventional and New Source of Energy Energy is one of the most important component of economic Biomass, coal, Geothermal Energy, hydroelectric energy, Nuclear Energy, oil and natural gas, solar energy, and wind energy. Biomass is a RENEWABLE ENERGY source that comes from plants and other organic materials. Biomass can be used to … Read more
Electrostatic The basic principle of Electrostatics is based on the fact the electric charges attract or repel other charges depending on their relative signs and the law of force is given by Coulomb‘s law. Coulomb’s law states that: The magnitude of the electrostatic force of interaction between two point charges is directly proportional to the … Read more
Electro Magnetic Induction When a DC current passes through a long straight conductor a magnetising force, H and a static Magnetic Field, B is developed around it If the wire is then wound into a coil, the magnetic field is greatly intensified producing a static magnetic field around itself forming the shape of a bar … Read more
Development of non-conventional sources of energy is of prime importance for the sustainable and Energy Resources are depleting at an accelerated rate and non-conventional resources could play a leading role in Energy Security in the state. Non-Conventional energy resources could minimise the transmission cost and energy divide between the remote locations [su_heading size=”21″]Solar[/su_heading] Rajasthan … Read more
Ray Optics The wave model of Light has one serious drawback, though: Unlike other wave phenomena such as Sound, or surface waves, it wasn‟t clear what the medium was that supported light waves. Giving it a name – the “luminiferous aether” – didn‟t help. James Clerk Maxwell‟s (1831 – 1879) theory of electromagnetism, however, showed … Read more
Rotational Motion A rotation is a circular movement of an object around a center (or point) of rotation . A three-dimensional object always rotates around an imaginary line called a rotation axis. If the axis passes through the body’s center of mass, the body is said to rotate upon itself, or spin. A rigid body … Read more
A tsunami is a very long-wavelength wave of water that is generated by sudden displacement of the seafloor or disruption of any body of standing water. Tsunami are sometimes called “seismic sea waves“, although they can be generated by mechanisms other than Earthquakes. Tsunami have also been called “tidal waves”, but this … Read more

Here is a list of subtopics without any description for Surface Waves: Capillary waves Gravity waves Internal waves Langmuir waves Solitons Tsunami Wind waves Surface waves are waves that occur at the interface between two fluids or a fluid and a solid. They are caused by the disturbance of the interface, and can be either … Read more
