Though the particle in a box (infinite potential well) seems like a very unrealistic potential, it can actually be used to explain a bit about how humans see. The important light-absorbing molecule in human eyes is called retinal. Retinal consists of a chain of carbon atoms, roughly 1.5 x 10-⁹ m long. An electron in this long chain molecule behaves very much like a particle in a box. Constants Periodic Table Find the wavelength of the photon that must be absorbed by an electron to move it from the nth state of a box to the (n + 1) th state. Assume that the box has length L and that the electron has mass m. Express your answer in terms of n, L, Planck's constant (divided by 2π) ħ, the speed of light c, and m. ► View Available Hint(s) IVE| ΑΣΦ α Submit B V ग A Σ Y P Φ 4mcL² (2n + 1)лh 8 0 € Previous Answers T Y Ω n Ф ħ Ꮎ E K λ μ y @ ?
