750 | 400 11. Short answer. Refer to the color wheel on the right. If a solution is illuminated with white light and absorbs all wavelengths between 480 and 560 nm, what color would it appear to be? Violet Red 430 630 Blue Orange 480 590 Green Yellow 560 12. Short answer. You will need the color wheel on the right. Look at the absorption spectrum of the solution shown on the right. What color would this solution be? 600 13. Short answer. Look at the image of a spectrophotometer on the right. Structures/knobs A-E are labeled. Which knob will you have to use to zero the instrument itself? 20D BIOLOG. 14. Short answer. According to Beer's Law, given that Molar Absorptivity and path length is usually constant, Absorbance A is directly proportional to 15. Choose the one answer that fits best. Which of these is not standard components of a spectrophotometer? a. A sample chamber to hold your tube with sample solution b. A light source c. A prism or grating to filter out certain wavelengths of light d. A blank e. A sensor/detector 16. True or False. If false, correct. A spectrophotometer directly measures the concentration of a substance.
