Sunscreen contains compounds that absorb ultraviolet light. When sunscreen is applied to the skin, it prevents ultraviolet light from reaching the skin. The graph that follows shows the absorbance of light as a function of wavelength for two different compounds (2-EHMC and TDSA) common in sunscreen. Absorbance is a measure of the amount of light absorbed by the compound - the higher the absorbance, the. more light is absorbed. Study the graph and answer the questions. 0.6* UV-B UV-A 0.5 0.4 · 2-EHMC 0.3 TDSA 0.2 0.1 290 300 310 320 330 340 350 360 370 380 390 400 Wavelength (nm) 2018 Peaon idcation, .
