Yellow light (570-590 nm) and Orange light (590-620 nm) are still being studied, and haven’t been isolated for use in light therapy devices yet. Some early studies have shown positive results for reducing inflammation and migraines, but green light has not been widely used in light therapy yet. Green light (495-570 nm) is only recently being studied for therapeutic effects. Blue light is also isolated and used in light therapy treatments for facial skin and acne. Blue light is good at making things bright, which is why it’s used in so many electronics. īlue light (450-495 nm) is best known for being isolated to produce the bright light of computer, television, and cell phone screens. Violet light is not used for light therapy because these wavelengths haven’t been shown to produce health benefits when they’re isolated. Violet light (380-450 nm) has the shortest waves on the visible spectrum. The visible light portion of the electromagnetic spectrum is separated into different wavelengths and colors of light. We can see the world around us because waves of visible light shine on objects, and reflect back to our eyes. We see these waves as the colors of the rainbow. Humans can only detect light with waves from 400 nanometers to about 700 nanometers. When we think about light, we usually think about visible light. In between, on a tiny sliver of the spectrum, we see visible light in all its colors and glory. On the other end of the spectrum are high-energy radio and micro waves that have the shortest wavelengths. At one end are low-energy gamma rays and X-rays that have the longest wavelengths. The electromagnetic spectrum is very wide. The electromagnetic spectrum contains all the light that exists, organized in order of wavelength. We measure light by wavelength, or the distance between each wave. Waves of light travel extremely fast through space and time, but all light is not the same. Waves of light are made of electricity and magnetism, which is why we call them electromagnetic waves. And only a few select wavelengths of light are suitable for light therapy treatments. Humans are able to see the world around us because wavelengths of light shine on the earth and reflect back to our eyes. Light comes to the earth from the sun, in the form of electromagnetic waves that carry energy. Have you ever wondered what light really is? In this post, we’ll explain what light is all about, and break down light wavelengths, light colors, and which wavelengths of light are used for light therapy. Conclusion: Red Light Wavelengths are Best for Color Light Therapy.Colors and Wavelengths of Visible Light.
