The Blue Light, its Benefits and Dangers

The Blue Light The visible light is a form of electromagnetic energy that forms part of what is scientifically known as the 'Electromagnetic spectrum.' The electromagnetic spectrum is made of electromagnetic particles that travel in waves. These waves emit energy and have different lengths and strengths. The shorter the wavelength, the higher the energy of these particles. These particles' wavelength is measured in nanometers (nm), with 1 nanometer equaling one billionth of a meter.  Each wavelength has its own color/name. They are grouped into gamma rays, x-rays, ultraviolet (UV) rays, visible light, infrared light, and radio waves.   Some of the radiations of the Electromagnetic spectrum are not visible and may be harmful to the human eye, such as the...
