Part A The color of dyes results from the preferential absorption of certain wavelengths of light. Certain dye molecules consist of symmetric pairs of rings joined at the center by a chain of carbon atoms, as shown in (Figure 1). Electrons of the bonds along the chain of carbon atoms are shared among the atoms in the chain, but are repelled by the nitrogen-containing rings at the end of the chain. These electrons are thus free to move along the chain but not beyond its ends. They look very much like a particle in a one-dimensional box. For the molecule shown, the effective length of the "box" is 0.85 nm. Assuming that the electrons start in the lowest energy state, what is the longest wavelength this molecule will absorb?

Yellow light with wavelength 600 nm is travelling to the right (in the positive x direction) in vacuum. The light is polarized along the +y direction. The light passes an observer X located on the x axis. (a) Draw a neat labeled movie mode vector picture of the wave at the location of AX. (b) If the wave were to represent blue light instead of yellow light, how would your diagram in part a change? Draw a new diagram to explain these changes. If there is no change, say so explicitly.

Three polarizing filters are stacked, with the polarizing axis of the second and third filters at angles of 24.0° and 62.0°, respectively, to that of the first. If unpolarized light is incident on the stack, the light has an intensity of 69.5 W/cm² after it passes through the stack. Part A If the incident intensity is kept constant but the second polarizer is removed, what is the intensity of the light after it has passed through the stack?
