Radio waves and microwaves are very important to us for communication.And for heating up left over pizza!ElectromagneticThey are both on the long wavelength end of the Electromagnetic Spectrum:Radio waves have wavelengths of 1 m up. The frequency at 1 m is 300 MHz. Microwaves have wavelengths ...
aMicrowaves, which have a higher frequency than ordinary radio waves, are used routinely in sending thousands of telephone calls and television programs across long distances. 微波,比普通的无线电波有一个更高的频率,在送定期地使用数以万计电话和电视节目横跨长的距离。[translate]...
Microwaves sent through the atmosphere will be absorbed by water so they can be used to monitor rain. The weaker the signal reaching the detector, the more rain the microwaves have passed through. Microwave transmissions Wireless technology uses microwaves and radio waves to transmit information. Adv...
Radio waves can also be emitted by the gases as well as the stars in space. Radio waves are mainly used for the communication sector. The radio waves have the lowest frequencies which are of the order of 3 kHz. Microwave: This type of radiation is found in mi...
The factors determining the interaction with biological material of radiowaves and microwaves at the macroscopic, cellular and molecular levels are briefly discussed in terms of the relevant physical parameters for electromagnetic radiat...

Define radios. radios synonyms, radios pronunciation, radios translation, English dictionary definition of radios. ) n. pl. ra·di·os 1. Electromagnetic radiation with lower frequencies and longer wavelengths than those of microwaves, having frequencies
theelectromagnetic (EM) spectrum. The EM spectrum is generally divided into seven regions in order of decreasing wavelength and increasing energy and frequency, according to theUniversity of Rochester. The common designations are radio waves,microwaves,infrared(IR), visible light,ultraviolet(UV),X-...
Using microwaves ultrasonic energy, electromagnetic waves to remove radioactive materials adsorved to the soildoi:US5262024 AApplying a desorbing wave energy to a soil matrix can effect desorption of ionic species which are associated with the matrix. This method is especially applicable to ...
Radio waves Microwaves Frequency value 30KHz-300GHz 300MHz-300GHz Penetration depth Comparatively, long-wavelength result in deep penetration in objects with high density Short wavelength results in less penetration on objects limited to small dimensions Uniform heating Radio wave heats the object uniform...
