full_question: This statement is applied separately to each component in multicomponent analysis. NanoDrop devices use this law to calculate the 260/280 ratio of DNA and proteins. This law can be written as I equals I-nought times the exponential of negative alpha times density times distance. A correction factor is added to this equation if turbidity is present. A parameter in this law has units of inverse molar times inverse centimeters. A calibration curve and a (*) blank are usually used to standardize before this law is applied, often to find the optimal wavelength. The cuvette path length in this law multiplies the extinction coefficient and concentration to give absorbance. For 10 points, name this law which governs spectrophotometers.
