What is Blue Light?

Light is made up of electromagnetic particles that travel in waves. The waves emit energy, and vary in length and strength.


Blue light has a very short wavelength, and therefore produces a higher amount of energy. 

The human eye is sensitive to only the visible light section of the spectrum, which we see as colors: violet, indigo, blue, green, yellow, orange and red.
