Astronomers have identified the source of strange radio flashes: a binary system containing a white dwarf, the remnant of a ...

Controlling where sound goes is difficult because of a phenomenon called diffraction – the tendency of sound waves to spread out as they travel. This effect is particularly strong for low-frequency ...

But de Ruiter didn’t think the star would be able to produce radio waves by itself. Something else had to be instigating it.The pulses differed from fast radio bursts, which are incredibly ...

However, a groundbreaking revelation has now uncovered the true source of these mysterious radio waves – and it’s not aliens, but a rare and unusual binary star system located over 1,600 light-years ...

THE modified form of the ionic deflexion theory of wave propagation, discussed by Messrs. Nichols and Schelling (NATURE, March 7, vol. 115, p. 334), appears to have been suggested in England and ...

In the years that followed, French engineer August Fresnel’s findings on diffraction ... Using this apparatus, he detected radio waves (which also traveled at the speed of light).

What are ham radios? In short, ham radio operators are amateur radio enthusiasts who communicate with one another via radio frequencies assigned specifically to this community by the Federal ...

However, traditional dark-field microscopy is limited by the diffraction barrier and often requires complex, bulky setups with precise alignment. Super-resolution imaging techniques, which can ...

The film explains the concept of electromagnetic waves, particularly focusing on their applications in radar, radio, and television. It describes how a crystal set functions as a simple radio receiver ...

AMONG the facts to be explained in a satisfactory theory of the propagation of radio waves over the earth's surface are the curvature of the rays in transmission between stations far apart ...
