EXPLANATION : From the above, it is clear that alpha ray , also called alpha particles alpha ray, contains two protons and two neutrons bound together into a particle just like a helium-4 nucleus, and it not an electromagnetic rays . WebX-ray computed tomography (CT) has been a widespread medical imaging modality for decades mainly due to its high imaging resolution. Compared to X-ray CT, microwave imaging (MWI) has several advantages, such as avoiding ionizing radiation, offering lower-cost portable hardware, etc. However, MWI lacks in terms of spatial resolution and …

Microwave is a form of electromagnetic radiation with wavelengths ranging from about one meter to one millimeter corresponding to frequencies between 300 MHz and 300 GHz respectively. Different sources define different frequency ranges as microwaves; the above broad definition includes both UHF and … See more Microwaves travel solely by line-of-sight paths; unlike lower frequency radio waves, they do not travel as ground waves which follow the contour of the Earth, or reflect off the ionosphere (skywaves). Although at the low end of the … See more The term microwave also has a more technical meaning in electromagnetics and circuit theory. Apparatus and techniques may be described qualitatively as "microwave" when the wavelengths of signals are roughly the same as the dimensions of the … See more Bands of frequencies in the microwave spectrum are designated by letters. Unfortunately, there are several incompatible band designation systems, and even within a … See more The short wavelengths of microwaves allow omnidirectional antennas for portable devices to be made very small, from 1 to 20 centimeters long, so microwave frequencies are widely used for wireless devices such as cell phones, cordless phones, … See more High-power microwave sources use specialized vacuum tubes to generate microwaves. These devices operate on different principles … See more Microwave technology is extensively used for point-to-point telecommunications (i.e., non-broadcast uses). Microwaves are especially suitable … See more Microwave frequency can be measured by either electronic or mechanical techniques. Frequency counters or high frequency heterodyne systems can be used. Here the unknown frequency is compared with harmonics of a … See more WebIn order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves. … dvd recorder/player amazon
