The behaviour of an electromagnetic wave in a substance depends on its frequency. The differing behaviours of different groups in the electromagnetic spectrum make them suitable for a range of uses.

There are seven types of electromagnetic (EM) waves, which make up the electromagnetic spectrum. Electromagnetic waves are transverse waves, and travel at the speed of light. Different types of ...

Electromagnetic interference can be a serious problem for electronic devices, so shielding is usually placed around components. Now, engineers at Drexel University have found that a 2D material called ...

Electromagnetic radiation is a form of energy that includes radio waves, microwaves, X-rays and gamma rays, as well as visible light. When you purchase through links on our site, we may earn an ...

PITTSBURGH (KDKA) - The universe is full of waves, and they are not all created equally. Some are mechanical, and others are electromagnetic, even though they are all energy! Not all waves are created ...

An international research group has applied methods of theoretical physics to investigate the electromagnetic response of the Great Pyramid to radio waves. Scientists predicted that under resonance ...

Researchers at Drexel University have created “Faraday fabrics” that can block almost all electromagnetic waves. The key ingredient is a 2D material called MXene, and the development could help ...
