تعريف micro wave في الإنجليزية الإنجليزية القاموس.
a short electromagnetic wave (longer than infrared but shorter than radio waves); used for radar and microwave ovens and for transmitting telephone, facsimile, video and data
1) Any electromagnetic radiation with a wavelength between 1 millimeter and 1 meter 2) A point-to-point data transmission system employing electromagnetic radiation using a carrier frequency in the microwave region
(communications usage) High-frequency radio waves used for point-to-point and omnidirectional communication of audio, data and video signals Microwave frequencies require direct line-of-sight to operate; obstructions such as trees or building distort the signal
A form of electromagnetic radiation that is beyond the range of the visible light spectrum Microwaves have very high frequencies and wavelengths of 1 mm to 50 cm
That portion of the electromagnetic spectrum extending in frequency from 500 million cycles per second (500 MHz) up to the frequencies of visible light
High-frequency radio waves used for point-to-point and omni-directional communication of audio, data and video signals Microwave frequencies require direct line of sight between sending and receiving station to operate Microwave systems were the preferred method of communications transmission before the introduction of fiber optic
A term loosely applied to those radio frequency wavelengths which are sufficiently short to exhibit some of the properties of light Commonly used for frequencies from about 1 GHz to 30 GHz
Electromagnetic waves in radio frequencies above 890 MHz and below 20 GHz They only travel in straight lines, and are used for communication between satellites
Circuitry operating at frequencies where the wavelength is 1mm to 30cm (300GHz to 1GHz) - between radio and infra-red wavelengths Such frequencies on PCB require extreme attention to exact track form
To microwave food or drink means to cook or heat it in a microwave oven. Steam or microwave the vegetables until tender. to cook something in a microwave oven. Portion of the electromagnetic spectrum that is situated between radio waves and infrared radiation. Microwaves have wavelengths ranging from 30 cm to 1 mm, corresponding to frequencies from about 1 gigahertz (10^9 Hz) to 1 terahertz (10^12 Hz). They are the principal carriers of television, telephone, and data transmissions between stations on Earth and between the Earth and satellites. Radar beams are short pulses of microwaves used to locate ships and planes, track weather systems, and determine the speeds of moving objects. Microwaves are absorbed by water and fat in foodstuffs and produce heat from the inside (see microwave oven). Materials such as glass and ceramics do not absorb microwaves, and metals reflect them.

Place food in a microwave container (NOT metal) Set the microwave for the level and time and push, "Start" Wear oven mitts when removing something from the microwave
Loosely, an electromagnetic wave having a wavelength from 300 mm to 10 mm (1 GHz to 30 GHz) Note: Microwaves exhibit many of the properties usually associated with waves in the optical regime, e g , they are easily concentrated into a beam (188)
Line-of-sight, point-to-point transmission of signals at high frequency Many CATV systems receive some television signals from a distant antenna location with the antenna and the system connected by microwave relay
A Microwave (M/W) is a radio transmission using very short lengths, corresponding to a frequency of 1,000 megahertz (MHz) or greater A synonym is microwave radio
high frequency radio waves used for point-to-point communication of audio, video, and data signals They can be simplex (omnidirectional) or duplex The microwave spectrum is generally above 2 GHz Microwave transmission requires line of sight transmission between sending and receiving antennas
electromagnetic radiation which has a longer wavelength (between 1 millimeter and 30 centimeter) than visible light Microwaves can be used to study the Universe, communicate with satellites in Earth orbit, and cook popcorn
kitchen appliance that cooks food by passing an electromagnetic wave through it; heat is produced by the absorption of microwave energy by the water molecules in the food a short electromagnetic wave (longer than infrared but shorter than radio waves); used for radar and microwave ovens and for transmitting telephone, facsimile, video and data cook or heat in a microwave oven; "You can microwave the left-overs
