Much has been written about Albert Einstein. On the personal front, he is said to be a failed husband and a disappointed father. It’s really hard to know who this man really was. […]
The behavior of light in different frames of references led to a stunning paradox. It took the towering genius of Einstein to come to grips with this crazy paradox and led to the theory of relativity. […]
X-rays and gamma rays have short wavelengths, making them the most powerful rays in the electromagnetic spectrum. And, no definitive proof that they are dangerous has been uncovered yet. […]
Microwaves are caused by vibrations in the magnetic field. These waves have a wide range of applications in modern technologies. Most communication tools today work via these waves. […]
Radio waves, used by humans, include electromagnetic radiation with wavelengths between about a foot up to several miles long, the longest wavelengths. […]
The only way for us to know about electromagnetic radiation is for it to interact with matter. It turns out that there are only three basic ways electromagnetic radiation interacts with matter: they’re called transmission, absorption, and scattering. […]
The wavelength is equal to the speed of light divided by frequency for electromagnetic waves. The frequency is equal to the speed of light divided by wavelength for electromagnetic waves. […]
In describing the phenomena of electricity and magnetism, James Maxwell discovered that light is also a form of electromagnetism. […]
Michael Faraday concluded from experiments that the magnetic field produced by an electromagnet induced a current in the second circuit. This is the phenomenon of electromagnetic induction. […]
Electric circuits are important concepts that have practical applications in our daily lives. A circuit incorporates the idea of three different components and two main types of circuits; namely series and parallel circuits. […]
