Waves can be divided using several methods. And one such method of differentiating it is by the means of the medium in which they travel. As per the medium, the waves can be differentiated as mechanical and electromagnetic waves.

Tour of the Electromagnetic Spectrum

Waves come in many shapes and forms. While all waves share some basic characteristic properties and behaviors, some waves can be distinguished from others based on some observable and some non-observable characteristics. It is common to categorize waves based on these distinguishing characteristics. Longitudinal versus Transverse Waves versus Surface Waves. One way to categorize waves is on the basis of the direction of movement of the individual particles of the medium relative to the direction that the waves travel. Categorizing waves on this basis leads to three notable categories: transverse waves, longitudinal waves, and surface waves. A transverse wave is a wave in which particles of the medium move in a direction perpendicular to the direction that the wave moves.

Named after esteemed physicist James Clerk Maxwell, the equations describe the creation and propagation of electric and magnetic fields. Fundamentally, they describe how electric charges and currents create electric and magnetic fields, and how they affect each other. Magnetic field lines form loops such that all field lines that go into an object leave it at some point. Thus, the total magnetic flux through a surface surrounding a magnetic dipole is always zero. Field lines caused by a magnetic dipole : The field lines created by this magnetic dipole either form loops or extend infinitely. The principle behind this phenomenon is used in many electric generators.

Electromagnetic Waves

The electromagnetic spectrum is the range of frequencies the spectrum of electromagnetic radiation and their respective wavelengths and photon energies.. Electromagnetic Waves Basic idea of displacement current, Electromagnetic waves, their characteristics, their Transverse nature qualitative ideas only. These waves propagate in vacuum with speed c. In principle, electromagnetic spectrum extends over an infinite range of frequency. The energy of the electromagnetic wave is in the order of 15KV.

Segment F: Electromagnetic Wave Properties

Energy, a measure of the ability to do work, comes in many forms and can transform from one type to another. Examples of stored or potential energy include batteries and water behind a dam. Objects in motion are examples of kinetic energy.

Geosynchronous satellite is placed in the geosynchronous orbit with an orbital period matching the Earth's rotation period. These satellites take 24 hours to complete one rotation around the earth. However, the orbital plane for a typical geosynchronous satellite is generally not the equatorial plane.

Difference Between Mechanical and Electromagnetic Waves

Wave , propagation of disturbances from place to place in a regular and organized way. Most familiar are surface waves that travel on water , but sound , light , and the motion of subatomic particles all exhibit wavelike properties. In the simplest waves, the disturbance oscillates periodically see periodic motion with a fixed frequency and wavelength. Mechanical waves, such as sound, require a medium through which to travel, while electromagnetic waves see electromagnetic radiation do not require a medium and can be propagated through a vacuum.

Сьюзан неохотно кивнула. План неплохой. Когда служба безопасности извлечет Хейла из подсобного помещения и обвинит в убийстве Чатрукьяна, он скорее всего попытается шантажировать их обнародованием информации о Цифровой крепости.

 - Он опять замолчал. Сьюзан ждала продолжения, но его не последовало. - Больше трех часов. Стратмор кивнул. Она не выглядела взволнованной. - Новая диагностика.

 Да. Я решила ее издать. - Издать? - Он с сомнением покачал головой.  - Издать. - Некоторые идеи о протоколах вариативных фильтров и квадратичных остатках. - Стопроцентный бестселлер.

На брусчатке под ногами мелькали смутные тени, водка еще не выветрилась из головы. Все происходящее напомнило ему нечеткую фотографию. Мысли его то и дело возвращались к Сьюзан: он надеялся, что она уже прослушала его голос на автоответчике. Чуть впереди, у остановки, притормозил городской автобус. Беккер поднял. Дверцы автобуса открылись, но из него никто не вышел.

 - О… Боже ты мой… Фонтейн тоже все понял. Брови его поползли вверх. Он был потрясен.

Видел ли кто-нибудь из вас фильм Толстый и тонкий о Манхэттенском проекте. Примененные атомные бомбы были неодинаковы. В них использовалось разное топливо - разные элементы. Соши хлопнула в ладоши. - Он прав.

 Echo un poco de Smirnoff? - настаивал бармен.  - Плеснуть чуточку водки.

In physics , mathematics , and related fields, a wave is a propagating dynamic disturbance change from equilibrium of one or more quantities, sometimes as described by a wave equation.

Wave speed depends on the type of medium. 1. Mechanical waves- travel faster in solids & slowest in gases. 2. Electromagnetic waves- travel fastest in empty.

We explore electromagnetic wave properties and the electromagnetic spectrum.
