A sample is dissolved in water and analyzed using spectrophotometry. The sample shows an absorbance peak at a wavelength of 486 nm. Which one of the following adjustments would increase the absorption at that wavelength? Diluting the sample with additional water. Evaporating some of the water from the sample. Decreasing the path length, b, the light takes through the sample. Re-measuring the absorbance of the blank (water).
