so what's the problem with this blue light Tristan so we have you mentioned blue light is a high power light which is high energy light it's a low it's a low small wavelength so what are the wavelengths for blue light uh around like 400 or 420 to like 4 480 490 is this kind of the range nanometers nanometers yeah so the nanometers so just basic I know we're going to talk a lot about different areas of the electromagnetic spectrum so an electromagnetic wave is um you know it's it's photonic in nature and every electromagnetic wave is measured by its frequency its energy and its wavelength so frequency and and energy are directly correlated so if it's a higher frequency you get higher energy right and then the opposite for wavelength wavelength is inversely correlated with that so if you have a longer wavelength which is like infrared light you have lower energy and lower frequency so blue light typically ranges in the wavelength of you know 410 420 to like 490 nanometers and that is a higher energy wave length it's on the high end of the visible spectrum so out of all the colors we can see blue and then Violet are the highest energy and then ultraviolet which we can't see is even higher energy and shorter wavelength than that and higher energy means it's impacting our biology at a you know a stronger level and it's inducing more oxidative stress radical free radical production
