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 1.5×10−9m long. an electron in this long chain molecule behaves very much like a particle in a box.
1) find the wavelength λn 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.

According to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? view available hint(s) according to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? trigonal bipyramidal tetrahedral square planar determination of electron geometry requires information on whether the electron groups are lone pairs or bonding groups.
