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 ...

The National Council of Educational Research and Training (NCERT) has launched free online Physics courses for Class 12 ...

Did you know that the world around us is filled with different types of light waves ? From the warm glow of the sun to audible radio waves and invisible gamma rays, electromagnetic waves (action ...

THz waves, located in the far-infrared region of the electromagnetic spectrum, can be used to perform non-invasive imaging through opaque materials for security and quality control applications.

Researchers in Drexel University’s College of Engineering have developed a thin film device, fabricated by spray coating, that can block electromagnetic radiation with the flip of a switch. The ...

Pyramid power: radio waves incident from above are focussed to a region below the pyramid (shown in red). Also in red are the waves concentrated in the rectangular King's Chamber within the pyramid.
