- Name the colors in a color spectrum of visible light from low to high wavelength.Assume that you have an “X” solution that you do not know its concentration. But you have other X solutions with known concentrations and you know X solution absorbs maximum light at 575 nm. To calculate the unknown solution concentration, you have done some spectrophotometric measurements and obtained data given below. Prepare a standard curve by using the absorbance of known concentrations (Hint: you can learn how to prepare a standard curve by using Excell from youtube). Calculate the concentration of unknown.In your own words define what is Dark matter?
