Use of information technology in administration Public Administration, governed by bureaucratic structures built on rationale principles, that dominated the twentieth century, has failed to respond to the changing requirements of the present times. It is so because it tended to be rigid, laid too much emphasis on red-tapism; sap creativity; thwarted initiative; wore out dynamism … Read more use of information technology in administration

Basics of Computers Computer is a device that transforms data into meaningful information. Data can be anything like marks obtained by you in various subjects. It can also be name, age, sex, weight, height, etc. of all the students in a class. A computer is a programmable machine. It allows the user to store all … Read more Basics of computers

Electromagnetic Wave Electromagnetic Wave are waves composed of undulating electrical fields and magnetic fields. The different kinds of electromagnetic waves, such as light and radio waves, form the electromagnetic spectrum. All electromagnetic waves have the same speed in a vacuum, a speed expressed by the letter c (the speed of light) and equal to about … Read more Electromagnetic Waves
Semiconductor Devices:- Semiconductor devices are electronic components that exploit the electronic properties of semiconductor materials, principally silicon, germanium, and gallium arsenide, as well as organic semiconductors. Semiconductor devices have replaced thermionic devices (vacuum tubes) in most applications. There are two basic groups or classifications that can be used to define the different semiconductor types: Intrinsic … Read more semi conductor devices
Nuclear physics Atoms in nature generally are electrically neutral, as they have equal numbers of protons in the nucleus and orbiting electrons. However, within the nucleus there are other particles called neutrons, which are electrically neutral but have about the same mass as protons. There are two numbers used to characterize a nucleus: Z, the … Read more Nuclear physics
The photoelectric effect The photoelectric effect is the emission, or ejection, of electrons from the surface of, generally, a metal in response to incident light.A material that can exhibit The photoelectric effect is said to be photoemissive, and the ejected electrons are called photoelectrons. The process was discovered by Heinrich Hertz in 1887. Attempts to … Read more Photo electric effect

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 Ray optics
