Why were the absorbance measurements recorded at lambda max (504 nm)?   Question 1 options:   at lambda max impurities in the sample do not absorb any light   Because the allura red dye absorbs red color at 504 nm   at lambda max the absorbance is the most sensitive to dye concentration   at lambda max the absorbance is the least sensitive to dye concentration
