The color of the laser which would be appropriate in removing the red port-wine stain is to be identified. Concept Introduction: Absorption spectroscopy is a technique of measuring the absorption of radiation. The color of any substance depends on the respective colors of the light absorbed and reflected by its molecules or atoms. Light has both particle and wave properties. Hence, it has dual characteristics. The wavelength of light determines both its color and energy. Electromagnetic radiation ranges in wavelengths from the gamma waves to the radio waves region. In the visible region, white light contains the spectrum of wavelengths ranging from 400 nm − 780 nm .
