Answer:
Visible light is known to have wavelengths in the range of 400 to 700 nanometres (nm), or 4.00 × 10⁻⁷ to 7.00 × 10⁻⁷ m, which is between infrared which has longer wavelengths and ultraviolet which has shorter wavelengths. The wavelength of visible light implies it has a frequency of roughly 430 to 750 terahertz
