Microwave power transmission (MPT) is one of the applications of microwaves to transmit power from one place to another place without the need for wires. It is the type of the Electromagnetic Radiations‚ one of the wireless energy transfer methods. Introduction: Firstly‚ we will talk about the term Microwaves‚ Microwaves can also be termed as Radio waves having wavelengths ranging from one millimeter to one meter and the frequencies from 300MHz to 300GHz. These are also known as millimeter waves

Chernobyl‚ Ukraine Nuclear Power Plant Meltdown The accident at the Chernobyl Nuclear Power Plant in Ukrainian produced a plume of radioactive debris that drifted over parts of the western USSR‚ Eastern Europe‚ and Scandinavia. The accident‚ which occurred on April 26‚ 1986‚ was the worst nuclear power accident in history. Large areas of the Ukrainian‚ Belorussian‚ and Russian republics of the USSR were contaminated‚ resulting in the evacuation of roughly 200‚000 people. The accident raised

A radioactive element is one that gives off radiation and breaks down to form a different element. Radon is a radioactive element.

The wave model can be used to explain how current technologies transfer information * describe the energy transformations required in one of the following: mobile telephone‚ fax/ modem‚ radio and television Energy transmission in mobile telephone: sound wave energy (input sound) -> electrical (in transmitting phone) – > radio wave (transmit signal) -> electrical (in receiving phone) -> sound (output sound) * describe waves as a transfer of energy disturbance

but on plants. In brief‚ we can say that microwaves are electromagnetic waves with wave length longer than those of terahertz (THz) frequencies‚ but relatively short for radio waves. There are lots of sites contaminated by microwave radiation from cellular radiation‚ power plants and high voltage towers‚ etc….. These affect the plants development‚ which drew our attention towards this project. Our hypothesis is that different doses of microwaves affect plant growth and development. To prove this

An adventure into Astronomy Late at night I like to go into my backyard with a telescope and look at the stars that far away in the night sky. The view of thousands of stars feeds me with wonder and amazement about both the stars origins‚ and what treasures they may hold floating around them. All life needs a host star to form around‚ and all life comes from the ashes of these once glorious masses of gas. Astronomy offers us a great view of the universe around us‚ you can join me and others‚

energy pulls‚ pushes‚ twists‚ turns and throws. Radiant Energy Visible light is electromagnetic energy emitted at wavelengths our eyes can see. Electromagnetic energy emitted at wavelengths we cannot see may take the form of infrared radiation‚ ultraviolet radiation‚ X-rays‚ gamma rays‚ and radio waves. Gamma rays have wavelengths much shorter than visible light. Radio waves are the opposite. Their frequencies are far longer than the longest waves our eyes can see. Electrical Energy Electrical
