New research on the last, hidden part of the electromagnetic spectrum is producing new, safe and non-destructive tests for medicine, security and industrial quality control. New European research on ...

The range of colors or wavelengths that a telescope can observe depends on the design of both the telescope itself and the cameras attached to it. For instance, if you’re building a telescope that ...

Electromagnetic wave is a wave consisting of electric and magnetic fields oscillating and traveling on the same direction. Light is an example of an electromagnetic wave and light in general is part ...

The Electromagnetic Battle Management system will be a new start in FY21. Radio waves, used with the direction finding system that the soldiers in the picture are testing, are one part of the ...

Terahertz radiation, or T-rays, has barely been exploited compared to most of the rest of the electromagnetic spectrum. Yet T-rays potentially have applications in next-generation wireless ...

For simplicity, let's consider one of the waves describing either the electric or magnetic field displayed in Figure 3.1. This wave can be considered as a component of the more complex electromagnetic ...

The combination of electric and magnetic fields at right angles produces radio waves. These waves occur at different frequencies, and the range of useful frequencies is called the electromagnetic ...

One of the landmark discoveries of 19 th century physics was the realisation that electricity, magnetism and light are all connected. Experiments had already shown that the movement of electrical ...

Electromagnetic waves are members of a family of waves with common properties called the electromagnetic spectrum. The electromagnetic spectrum is a continuous range of wavelengths. The types of ...
