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 ...

Back to our radio signal. The electrons in our wire are moving, but not in one direction. These electrons are moving back and forth. Actually, the wave displayed in the activity is a ...

The team tracked the signal back to a strange binary system containing a dead star or " white dwarf " and a red dwarf stellar ...

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 ...

trumpet the sound from the trumpet comes from a vibrating column of air created by buzzing lips of the trumpeter A sound wave is a longitudinal wave. When an object vibrates it produces a ...

It’s never too late to change the frequency of the frontier areas by changing the frequency of the airwaves that are at the ...

Astronomers say they have traced a mysterious pulsing in the Milky Way to a surprising source: a dead star locked in a dance ...

What causes waves What different devices have been invented to use wave energy What the advantages and disadvantages of wave energy are This resource is suitable for energy and sustainability ...

Astronomers have finally traced a strange class of radio signals—long a cosmic mystery—to a binary star system made up of a ...

Electromagnetic radiation is the general term for the more familiar light and radio waves, but also includes gamma rays, x rays, ultraviolet rays, and infrared. All of these forms of electromagnetic ...

It's always a great day to be a Bronco—especially when that day includes being recognized as the best college radio station ...
