MICROWAVES
3 Maliya Aleman............................................
What is a Microwave?
A microwave is an electromagnetic wave with a wavelength in the range of 0.001–0.3 m, shorter than that of a normal radio wave but longer than those of infrared radiation. Microwaves are used in radar, in communications, and for heating in microwave ovens and in various industrial processes.
Everyday Applications
Some everyday items that consist of microwaves would be TV antennas(if those still exist), FM radio antennas, Microwave ovens, or even radar runs that policeman use.
Health Impacts
Health impacts of microwaves on the human body only occur when the frequency of the item is low. So, the lower the frequency, the higher the hazard. The higher frequency, the lower the hazard.
Frequencies lower than 3,000 megahertz can penetrate the outer layer of skin and be absorbed in the underlying tissues. Which can result in burns and cataracts is in the eyes.
Wavelength Range
The wavelength range of a microwave is from 30 centimeters (12 inches) to 3 millimeters (0.12 inches).
frequency range
The frequency of microwaves range from 10 megahertz to 300,000 megahertz
velocity in a vacuum
The velocity of a microwave is 3x10^8 m/s, which is also the same as electromagnetic wave since they're in the same spectrum.
Electromagnetic Spectrum: Microwaves
In the video it is being explained how microwaves are used in terms of whether forecast and finding the measurements of arctic sea ice. The Japanese used microwaves for forest mapping and finding surface-soil moisture. It also explains how microwaves are used to study the composition of cosmic dust or a supernova.
This article, "The Dangers of Microwaves Revealed" is about the negative health impacts that microwave ovens have on the consumer. That being that they are capable of giving off an infection called leukocytosis. It is also explained how microwave ovens are capable of even causing cancer.
