a) The three molecules naphthalene (C10), anthracene (C14), and tetracene (C18) have spectra shown below. Note that the y-axis is base 10 logarithmic with units of M-1 cm-1. If anthracene is used as a sunblock in sunglasses 1 mm thick, what concentration is needed to get
99% absorbance?

(b) Which molecule(s) are likely to be colored?

(c) Using elementary quantum principles, explain why tetracene absorbs at the longest weavelength
