Which of the following statements is/are correct? i. This wavelength of light is emitted by the sample. ii. This wavelength of light is absorbed by the sample. iii. This wavelength of light is transmitted through the sample. iv. This wavelength of light is reflected by the sample. (i) only (ii). (iii), and (iv). (0). (ii), and (iii) None of the statements are correct
Absorbance (arb.units) 200 300 400 500 600 Wavelength (nm) 700 800 Absorbance (arb.units) 200 300 400 500 600 Wavelength (nm) 700 Two students obtain absorption spectra of the same sample. The spectrum on the left was obtained by student A and the spectrum on the right by student B. The reference spectrum only has one singlet peak at 630 nm. What is the MOST LIKELY reason the students have differing spectra? O Student A did not properly clean the outside of the cuvette before obtaining the spectrum. O Student A did not use a solvent blank. O Student A used a different spectrophotometer than Student B. Student A used a cuvette with a longer path length than Student B.
