What's Really Going on in Hawaii

Blue wavelength in nanometers is from 450-495 nanometers, but when you convert the nanometers to terahertz it comes out as 👉666.2 in terahertz. If you are using a blue laser against a blue target with the same wavelength, the wavelength of the laser will be reflected out of the target causing little to no damage, when other targets of different wavelengths will be completely burned.
