NM is a millionth of a millimeter or a billionth of a meter, and is a standard expression for shortwaves.
Wave frequency is related to wave energy. Since all that waves really are is traveling energy, the more energy in a wave, the higher it’s frequency. The lower the frequency, the less energy in the wave. When it comes to light waves, violet is the highest energy color and red is the lowest.
Color has a huge impact on us, whether we are conscious of it or not. By using color consciously, we can create profound change in our physical, mental, and spiritual well-being. Not only can we use colored light- but colored everything! From the food that we consume, to our clothes and home decor, color your world, and your life will be colorful.
