(a) The true absorbance of a sample is 1.500, but 0.50 % stray light reaches the detector. Find the apparent transmittance and apparent absorbance of the sample. (b) How much stray light can be tolerated if the absorbance error is not to exceed 0.001 at a true absorbance of 2 ? (c) A research-quality spectrophotometer has a stray light level of <0.00005 % at 340  nm. What will be the maximum absorbance error for a sample with a true absorbance of 2 ? Of 3 ? | Numerade
