dye molecule has electrons that are free to travel up and down a chain of atoms, giving electron energy states that are given by the particle-in-a-box model, with En=(0.34eV)n2 . Part A What are the three longest wavelengths of visible light that the molecule will absorb? Enter your answers in nanometers in descending order separated by commas. λ 1 ,λ 2 , λ 3 =
