what is a wave? a wave is a disturbance which travels through a medium and transfers energy from one point to another without causing any permanent displacement of the medium itself. if a stone is dropped in a pond or swimming pool‚ ripples or waves are seen spreading on the surface of the water from the point where it was dropped. the water itself does not move in the direction of the ripples‚ but the waves transfers energy from one point to another. there are two major classes of waves ; mechanical

The Elliott wave principle is a form of technical analysis that attempts to forecast trends in the financial markets and other collective activities. It is named after Ralph Nelson Elliott (1871–1948)‚ an accountant who developed the concept in the 1930s: he proposed that market prices unfold in specific patterns‚ which practitioners today call Elliott waves. Elliott published his views of market behavior in the book The Wave Principle (1938)‚ in a series of articles in Financial World magazine in

Waves are mainly known for their way of transferring energy from one place to another without transferring any matter.Transverse and longitudinal are waves in which can be related to one another in some kind of way. A transverse wave is a wave in which vibrates perpendicular to the direction of the waves motion. As a transverse wave travels through a medium‚ the individual particles of the medium move perpendicular to the direction of the wave travel. They may occur in a string‚ in the surface of

Concept In The Elliott Wave Principle — A Critical Appraisal‚ Hamilton Bolton made this opening statement: As we have advanced through some of the most unpredictable economic climate imaginable‚ covering depression‚ major war‚ and postwar reconstruction and boom‚ I have noted how well Elliott’s Wave Principle has fitted into the facts of life as they have developed‚ and have accordingly gained more confidence that this Principle has a good quotient of basic value. "The Wave Principle" is Ralph Nelson

Stoneley-wave attenuation and velocity are sensitive to fracture and formation permeability‚ especially at low frequencies. Stoneley-wave velocity declines‚ and its attenuation increments‚ as permeability increments. Beginning endeavors (started in the 1970s) to get permeability information from Stoneley information was unsuccessful because neither the significant low-frequency instruments nor the proper handling techniques had been created. The parallel advancement of present day multi-pole array

The basis for an understanding of sound‚ music and hearing is the physics of waves. Sound is a wave which is created by vibrating objects and propagated through a medium from one location to another. In this unit‚ we will investigate the nature‚ properties and behaviors of sound waves and apply basic wave principles towards an understanding of music. As discussed in the previous unit of The Physics Classroom‚ a wave can be described as a disturbance that travels through a medium‚ transporting

SUBJECT: ANTENNAS AND WAVE PROPAGATION 1. Define an antenna. Antenna is a transition device or a transducer between a guided wave and a free space wave or vice versa. Antenna is also said to be an impedance transforming device. 2. What is meant by radiation pattern? Radiation pattern is the relative distribution of radiated power as a function of distance in space .It is a graph which shows the variation in actual field strength of the EM wave at all points which are at equal distance from the

Practise essay on Change In the novel The Wave by Morton Rhue we see change occur in this novel when a classroom experiment designed to show students how to make people change and conform their behaviour to fit certain rules. The classroom experiment that the teacher created was the catalyst that caused throughout the schools behaviour and the students behaviour and attitude. Robert Billings is a student who rarely pays attention in class and is always getting low marks and sleeping in Ben Ross’s
