Different types of electromagnetic radiation spectrum with examples

What is Electromagnetic Spectrum? The word spectrum comes from a Latin word meaning “form” or “appearance”. Other familiar words from the same root include “spectacle” and “species.” Newton introduced word to describe the rainbow-like image that resulted when a beam of sunlight passed through a glass prism. Today we speak of the electromagnetic spectrum to indicate the many different kinds ...

Wheatstone bridge strain gauge

The Wheatstone Bridge: The Wheatstone bridge circuit is widely used to precisely measure resistance. Also, the bridge is used in conjunction with transducers to measure physical quantities such as strain,temperature , and pressure. Transducers are devices that sense a change in a physical parameter and convert that change into an electrical quantity such as a change in resistance. For example, a ...

Continuity equation derivation in fluid mechanics with applications

General Concept of Fluid Flow One way of describing the motion of a fluid is to divide the fluid into infinitesimal volume elements,which we may call fluid particles,and to follow the motion of each particle. If we knew the forces acting on each fluid particle,we could then solve for the coordinates and velocities of each particle as functions of the ...

Terminal Velocity formula

What is Terminal Velocity? “When a magnitude of the drag force becomes equal to the weight,the acting force acting on the droplet is zero. Then the droplet will fall with constant speed called terminal velocity.” Before we going to discuss terminal velocity,we will first shortly explain viscosity and Stokes law. What is viscosity? “The fractional effect between different layers of ...

what are Elastic and Inelastic Collisions?

What is a Collision? In a collision a relatively large force acts on each colliding particle for a relatively short time. The basic idea of a collision is that the motion of the colliding particles (or of at least one of them) changes rather abruptly and that we can make a relatively clean separation of time that are “before the ...

Inductor and inductance:types and applications

What is Inductor and what does it do? When a length of wire is formed into a coil,it becomes a basic inductor. The term coil and inductor are used interchangeably.Current through the coil produced an electromagnetic field, as illustrated. The magnetic lines of force around each loop (turn) in the winding of the coil effectively add to the lines of ...

Types of radioisotopes and their uses in medicine agriculture

What are the uses of Radioisotopes? Nuclei which do not emit radiations naturally are called stable nuclei. In general, most of the nuclei with atomic number 1 to 82 are stable nuclei. While the elements whose atomic number is greater than 82 are naturally unstable. They emit different types of radiations, all the time, and hence continuously change from one ...

Difference between nuclear fission and nuclear fusion

Nuclear Fission “Such a reaction in which a heavy nucleus like that of uranium splits up into two nuclei of equal size along with the emission of energy during the reaction is called fission reaction” Otto Hahn and Fritz Strassmann of Germany while working upon the nuclear reactions made a starling discovery. They observed that when slow moving neutrons are ...

Radioactivity:definition,types,uses & examples

What is Radioactivity? It has been observed that those elements whose charge number Z is greater than 82 are unstable. Some invisible radiations, that can effect the photographic plates emanate out of these elements. Such elements are called radioactive and the phenomenon is called radioactivity. The radiations coming out of the radioactive elements are called alpha (α) , beta (β),and ...

Radioactive half life:Definition,formula and examples in physics

What is Half Life of Radioactive Element? “The Time during which half of the unstable radioactive nuclei disintegrate is called the half-life of the sample of radioactive element.” We have seen that whenever an α or β-particle is emitted from a radioactive element,it is transformed into some other element. This radioactive decay process is quite random and is not subjected to any ...
