CHALK TALK: ELECTROMAGNETIC SPECTRUM

submitted by: nsf

The electromagnetic spectrum is the range of all possible wavelengths of energy, including the visible light that makes plants grow, and the infrared that your remote control uses to command your television. Wavelength decreases as frequency increases, so we can say that it is inversely proportional to both frequency and energy.

Resonance: Radio, Wineglasses, Opera Singers and Cycles

submitted by: RayTomes
Resonance is the quality of transmitting even tiny signals between systems that are tuned to the same frequency. Given that cycles of common period are found pervading many different disciplines, perhaps an explanation may be found in resonance. An example is the 160 minute (and associated 80 minute cycle) cycle, found in biological systems, outer planetary spacings, the rotation rates of planets, asteroids and binary stars, solar oscillation and flux and galactic cores. A cosmic pervading...
