What Is Blue Light? The Electromagnetic Spectrum

All light, including blue light, is made up of electromagnetic particles that travel through the air to our body in waves. These waves emit energy and depending on the colour, the strength and range of the light can differ. A shorter wavelength is associated with higher energy levels. The unit of measure for light is nanometres (nm) with 1 nanometre equalling just 1 billionth of a meter. Grouped up these items create the electromagnetic spectrum, but only some of these are visible to us.Electromagnetic Wavelengths- Gamma Rays- X-Rays- Ultraviolet (UV) Rays- Visible Light- HEV Light (High Energy Visible)- Infrared Light-
