Long-wavelength electromagnetic radiation

When stressed, a material releases various types of emission prior to, during, and subsequent to ultimate failure. This emission includes electrons, positive ions, neutral molecules, and photons - including long wavelength electromagnetic radiation (radio waves), which we have collectively termed fracto-emission (FE). 

Fracto-emission (FE) is the emission of particles and photons accompanying deformation and fracture. These emissions typically include electrons (EE), positive ions (PIE), neutral atoms and molecules, including both ground state neutrals (NE) and excited neutrals (NE ), visible photons (phE)—also called triboluminescence in this context, and long wavelength electromagnetic radiation (RE radio emission). 

In this section we describe the peeling of two common pressure-sensitive adhesives in terms of the characteristics of the photon emission (phE) and long-wavelength electromagnetic radiation (RE) accompanying this form of fracture. In particular, we show that the emission is in the form of bursts, and determine the time distributions of the phE bursts, the time and intensity correlations of the phE and RE bursts,( i) the optical spectra of the phE(45) and the spatial distributions (i.e., images) of the phE for particular substrates.( 3,46,83)... 

The wavelength is rather long— 3.40 m—but radio waves are known as long wavelength radiation. See Figure TA for a sense of the wavelengths of electromagnetic radiation. 

Radio waves and other radiation with a long wavelength and low frequency are at the low energy end of the electromagnetic spectrum. 

Light, or electromagnetic radiation, has both wave and particle or unit character associated with its behavior. Wavelengths range from very short (10 meters) for the "gamma rays" that accompany nuclear decay to quite long (10 meters) for radio waves. 

This equation says that frequency and wavelength are inversely related Electromagnetic radiation with a long wavelength has a low frequency, and radiation with a short wavelength has a high frequency. 

Mr. Plex nods. Sir, the electromagnetic spectrum includes lots of wavelengths that we can t see. Do stars exist that radiate mostly in wavelengths that we can t see Yes, I think of them as ghost stars. For example, we can t see very cool stars with very long wavelengths. ...
