Light travels from the sun to the earth, a distance of about 145 000 000 km, through space containing very little material. When absorbed by a surface it is converted into heat, a form of energy. Energy must therefore have arrived from the sun across this immense distance. In fact almost...
The electromagnetic spectrum describes the range of electromagnetic waves ranging from visible light to the gamma rays. It is an essential aspect of science, and knowing this area of the universe is essential. In this article , I will go over some of the most important aspects of this range ...

The “micro-” prefix refers to the fact that microwaves are small in comparison to radio waves, the next on the spectrum. You may remember that tea—which is full of water—heats up quickly in your microwave oven, while a ceramic cup—from which water has been removed by baking—stays ...

region of the electromagnetic spectrum where the wavelength of light is measured from 1 mm to 400 nanometer. Discernible to humans as heat. Discovered by W. Herschel by dispersing sunlight through a prism and measuring the temperature increase just beyond the red end of the spectrum. ...
Remote Sensing refers to the practice of deriving information about the Earth’s land and water suces using images acquired from an overhead perspective, using electromagnetic radiation in one or more regions of the electromagnetic spectrum, reflected or emitted from the Earth’s suce. ( ) A. 正...
