Introduction to Modern Physics

Introduction to Modern Physics Introduction to Modern Physics. The term recent physics refers to the post-Newtonian beginning of physics. Put purely, modern physics agreements with the fundamental construction of the tiniest particles in nature ("quantum" mechanics), as well as a laborious sympathetic of the important communication of atoms, unspoken as forces. Small speeds and large…

Physical Optics

Physical Optics Physical Optics. In physics, physical optics, or movement optics, is the division of optics which educations interfering, deflection, polarity, and other miracles for which the beam estimate of symmetrical optics is not valid. This usage inclines not to contain special effects such as substantial sound in visual communiqué, which is considered in the…

Geometrical Optics

Geometrical Optics. Light. is a form of radiant energy or external cause which creates sensation of light when enters into our eyes. This radiant energy travels from one place to another place in the form of transverse waves. Ligh tpropagates in a straight line in homogeneous medium. But when light is incident on a secondmedium…

Semiconductor and Electronics

Present ear is called the era of Electronics. Now-a-days application of electronics are seen in our everyday life-like radio, television, VCR, computer, interne, mobile, i-pad etc. Electronics is originated from the word electron. Electronics in a branch of physics dealing with the flow of electrons in devices like valves or semi-conductor devices. The working of…

New Curriculum Physics Note of Current Electricity

Electric current is the rate of charge flow past a given point in an electric circuit, measured in Coulombs/second which is named Amperes. In most DC electric circuits, it can be assumed that the resistance to current flow is a constant so that the current in the circuit is related to voltage and resistance by…

Static electricity

Static electricity is an excess of electric charge trapped on the surface of an object. The charge remains until it is allowed to escape to an object with a weaker or opposite electrical charge, such as the ground, by means of an electric current or electrical discharge. Static electricity is named in contrast with current…

Math of Thermodynamics in Physics

Math of Thermodynamics in Physics. Thermodynamics is a branch of physics concerned with heat and temperature and their relation to energy and work. It defines macroscopic variables, such as internal energy, entropy, and pressure, that partly describe a body of matter or radiation. It states that the behaviour of those variables is subject to general constraints,…

Electronics

Electronics Electronics deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes and integrated circuits, and associated passive interconnection technologies. The nonlinear behaviour of active components and their ability to control electron flows makes amplification of weak signals possible and electronics is widely used in information processing, telecommunications, and signal…

Old Version Physics Notes

Old Version Physics Notes , Physics is "knowledge, science of nature", from physis, "nature" is a part of natural philosophy and a natural science that involves the study of matter and its motion through space and time, along with related concepts such as energy and force. More broadly, it is the general analysis of nature, conducted…
