Today, astronomers know that the majority of radiation, or light, present in the universe is invisible to human eyes. By looking at the universe in all possible wavelengths, scientists are piecing together a co
While the shortest and longest wavelengths of the visible light could be the most visible, the most energy efficient and aesthetically pleasing waves are the shortwave infrared (SWIR) and microwave frequencies.UVUltraviolet (UV) radiation is a part of electromagnetic spectrum. It can be used to ...
How is electromagnetic radiation arranged on the electromagnetic spectrum? How are mechanical and electromagnetic waves similar? How are Rossby waves distributed? Which electromagnetic waves emitted from the sun produce heat? Find the frequency of an infrared wave that has a vacuum wavelength of 5.5\cd...

He is widely heralded as a pioneer in electromagnetism, but he is also credited with discovering electromagnetic induction. Faraday also invented the electric motor, and besides his influential work in physics, he was the very first person to become appointed the prestigious position of Fullerian ...
Everything we see is made up of these 100 atoms in an unlimited number of combinations. How these atoms are arranged and bonded together determines whether the atoms make up a cup of water, a piece of metal, or the fizz that comes out of your soda can. Atoms are constantly in motion....
Why is electromagnetic force stronger than gravity? How does electricity cause magnetism? How does an electric current produce a magnetic field? How is electromagnetic radiation arranged on the electromagnetic spectrum? How is electromagnetism created?
A radio wave is an electromagnetic wave propagated by an antenna. Radio waves have different frequencies, and by tuning a radio receiver to a specific frequency you can pick up a specific signal. In the United States, the FCC (Federal Communications Commission) decides who is able to use whic...
Silicon has special chemical properties, especially in its crystalline form. Anatomof silicon has 14 electrons, arranged in three different shells. The first two shells — which hold two and eight electrons respectively — are completely full. The outer shell, however, is only half full, with ju...
