EM Spectrum

NPSGraphic

(The following is largely copied from an article on the same subject posted at the NPS web page.)

Most investigative effort in this community is focused on frequency. Whether via “full spectrum” photography, the latest EMF gadget, audio recorders, or DIY sensors and transmitters, the omnipresent trend is to find some telltale signature within the electromagnetic spectrum. There seems to be, unfortunately, a general misunderstanding of what is being “sensed” with our equipment. As usual, I am not claiming to have to have the one and only correct perspective on this subject. Nor do I intend to provide complete answers and information. I am asking the reader to evaluate any information they are given by taking on a little research of their own.

Whether we see it, hear it, or even feel it, energy as we perceive it, is part of the same spectrum; from static fields to slow (long wave length) approaching zero cycles per second and up to what we can assume is an infinitely fast (short wave length). “Bandwidth” is a range of frequencies within this spectrum associated with a specific topic. We are most familiar with bandwidths such as visual, audio, radio, infrared, and ultraviolet.

Static fields (those with essentially no measurable frequency) include; magnetics, batteries, and the potential charge that zaps our fingers when we reach for a door handle. An intriguing, yet seldom discussed, aspect of the EM Spectrum is brain waves; near 0 Hz up to about 60 Hz. Within this frequency range, we also find information covering the Schumann Resonance (frequencies associated with Earth’s magnetic field). I will not go into this sort of detail here but, I recommend anyone intrigued by paranormal events also look into frequencies of the brain and the Schumann Resonance. At 50 and 60Hz we find the most common frequency for household power. 20 Hz up to 20,000 Hz (20 kHz) is the

nominal frequency range for human hearing; also the likely range for EVP sources. Above 20 kHz we find bandwidths defined as radio and microwave. It is important to note that most EMF meters are designed to detect or measure frequencies from 20 Hz up into the microwave range. The intent being to monitor frequencies commonly used in our technologies which may damage our health. Beyond microwave we find, infrared, visual, and ultraviolet. All three will be discussed briefly later this week. Beyond ultraviolet we find x-ray, gamma, etc.

The “man-made frequency” misnomer:

Nature vibrates, typically with a sinusoidal wave shape. The EM spectrum is not man-made, it is entirely comprised of natural frequencies. Humans have found ways to utilize and manipulate certain frequencies into signals to enable technology. Our technology generally creates signal shapes other than sinusoidal and signal patterns intended to transfer information. There are no uniquely man-made frequencies, though signal patterns are often man-made. While determining the frequency of an EMF “spike” may ultimately be valuable in attempting to determine its origin, the frequency alone does not indicate a man-made origin.

Director / Chair Science at TEPI
Paranormal: Somewhat cliché but, my experiences began at a young age though I don’t recall making the “paranormal” association until the age of 9 when my grandmother died and returned for a visit. Through the years, I have given many phenomena more attention; from subtle dream images to apparent physical contact from “unseen” sources. I have been involved in independent research/study and investigation for about 30 years and began using some equipment about 20 years ago. I have been working with the Colorado based TEPI team since 2010. As a science oriented investigator, I am a bit of a contradiction. I believe the experience more so than the evidence. Simply because there can be many plausible explanations for most evidence. The experience on the other hand, can sometimes be very complex and difficult to explain easily. Professional: I have a Master of Science degree that essentially qualifies me to manage a multi-discipline team in their efforts to accomplish technical activities. (If I say more the MIB might show up.) My engineering background is primarily electronics but includes mechanical, astrophysics, and some aspects of thermal, optical, and audio. Previous careers were medical including paramedics and medical device technology (design, manufacturing, and training medical staff). I also dabbled heavily in photography before the wide spread use of digital imaging. Ideological: I was raised Presbyterian but allowed to find my own path. I studied Zen for a short time and explored many other faiths. In my late teens I attended a seminar on the subject of Quantum Physics and how it relates to our mind and consciousness; this was the turning point in my belief system. I did not become a scientific skeptic, I simply began to view nearly everything differently. I removed definitions I had learned and replaced them with relationships to my personal experiences and observations. Things once clearly defined as paranormal now had a plausible spin to them. Personal: In my spare time I write dark music, dark poetry, and horror/science fiction stories.
