How Is Light Energy? — Recommended Reading

Working at NASA’s Chandra X-ray Observatory, Arcand and Watzke specialize in communicating science to the public.  In their book Light: The Visible Spectrum and Beyond, Arcand and Watzke provide an enlightening story about what light is, way beyond the light we can see with our eyes, and how humanity has discovered and worked with light’s many properties.  Light illuminates this understanding with many beautiful pictures of the microscopic to the macroscopic.

“For many people, ‘light’ refers to what we as humans can detect with our eyes.  However, as we’ll discuss, this is merely one small slice of the whole range of light that exists.  That’s because light, including the human-detectable kind called visible light, is simply a form of energy.  The light we see with our eyes is a tiny fraction of the available light in the Universe…There are other types of light with less energy than visible light, and there are forms of light with much more energy” (Light, 10).  “All forms of light are energy, and the term scientists have come up with for this energy is ‘electromagnetic radiation’” (Light, 12).

“The terms light, electromagnetic waves, and radiation all refer to the same physical phenomenon: electromagnetic energy.  This energy can be described by frequency, wavelength, or energy. All three are related mathematically such that if you know one, you can calculate the other two” (Tour, 5).  “The electromagnetic waves that compose electromagnetic radiation can be imagined as a self-propagating transverse oscillating wave of electric and magnetic fields” (wiki).  In physics, “any simple vibration is described by three factors: its amplitude, or size; its frequency, or rate of oscillation; and the phase, or timing of the oscillations relative to some fixed time (see harmonic motion)” (

I open the possibility of a connection: when people describe their experience of an energizing group, they often describe the vibrancy of the group they experience, and the harmonic of the interactions.  They might be describing, consciously or unconsciously, their experience of the light they experience in the interactions with others.  I also offer the connection to the possibility that we humans are Homo lumens, beings of light, which I have discussed briefly in a previous blogpost.

  1. Thanks Jim! The HeartMath Institute pioneered research demonstrating the interaction of our electromagnetic energy and how it affects other living beings. Our emotions are carried in our electromagnetic fields primarily emanating from our heart. This “signal” affects those around us. What we emit is a choice and we can choose vibrancy and love over fear and negativity.

  2. Peter, I have been a student of the HeartMath work for many years, and deeply appreciate the direct, experiential basis that HeartMath brings to the pioneering research you mention. I frequently recommend your website and tools like the emWave, which I found particularly useful. All my best, Jim


    • That’s awesome Jim! I followed HeartMath for years too and decided to become a Certified HeartMath mentor and trainer. I teach a “Resilient Leader” program that is based on the HeartMath Resilience Advantage training program. What struck me after reading your post is an update to my workshop to include some of the concepts from your Vibrancy course! I’ll let you know how it goes! With gratitude, Peter
