Part A If you can read the bottom row of your doctor's eye chart, your eye has a resolving power of one arcminute, equal to 1.67x10-2 degrees If this resolving power is diffraction-limited, to what effective diameter of your eye's optical system does this correspond? Use Rayleigh's criterion and assume that the wavelength of the light is 570 nm

You and your roommate decide to install a 1200 lumen incandescent bulb in a simple light socket hanging directly in the center of the dorm room, with no diffuser or reflector. The bulb filament is exactly 2 feet from the ceiling. The walls and ceiling are all painted in a very dark color. Compute the illuminance falling on the exact center of the top of your dorm desk.

Antireflective Coating Part A A thin film of polystyrene is used as an antireflective coating for fabulite (known as the substrate). The index of refraction of the polystyrene is 1.49, and the index of refraction of the fabulite is 2.409. (Figure 1) What is the minimum thickness of film required? Assume that the wavelength of the light in air is 440 nanometers.

Two sources of electromagnetic waves (light waves) are emitting coherent waves at a frequency of 717 THz. These two sources are located a distance d apart and aimed at point A, as shown below. If the top source is located a distance 3.0 meters away from point A, find the minimum, nonzero, distance d that will give constructive interreference. Enter your answer in millimeters. 4₁ Laser Laser d A

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?
