Light is everywhere. The bright morning sun shining through your window as you wake up, the pale fluorescent lights above your cubicle at work, the warm glow of a fire — all lighting affects you, many times in an emotional way. Understanding the mechanics behind lighting will give you the tools you need to bring positive changes to your daily life.
So, what is light? The answer is complicated — even the physics community has trouble with this question — but we’ll attempt to shed some “light” on the topic. Light is an electromagnetic phenomenon with both electric and magnetic fields that are deeply interconnected. Light has a wavelength and a frequency. The frequency of visible light is referred to as color. A healthy human eye can see about 100 different shades of color — but many more colors exist.
