Part A A Michelson interferometer operating at a 500 nm wavelength has a 3.03-cm-long glass cell in one arm. To begin, the air is pumped out of the cell and mirror M2 is adjusted to produce a bright spot at the center of the interference pattern. Then a valve is opened and air is slowly admitted into the cell. The index of refraction of air at 1.00 atm pressure is 1.00028. How many bright-dark-bright fringe shifts are observed as the cell fills with air? ? Am =

Part A One day, after pulling down your window shade, you notice that sunlight is passing through a pinhole in the shade and making a small patch of light on the far wall. Having recently studied optics in your physics class, you're not too surprised to see that the patch of light seems to be a circular diffraction pattern. It appears that the central maximum is about 3 cm across, and you estimate that the distance from the window Estimate the average wavelength of the sunlight (in nm). shade to the wall is about 5 mn O 350 nm 450 nm O 550 nm O 650 nm O 750 nm Submit Previous Answers v Correct Part B Estimate the diameter of the pinhole (in mm).

You have been tasked with designing an anti-reflective coating for a camera lens. If the material you are using for the thin film, the antireflective coating has an n=1.38, and a coating is designed to eliminate reflected light of 550 nm in air when incident normally on glass (n=1.50), what thickness should the film be? A: what color would the lens look like B: why does this effect indicate that light behaves like a wave I already know the thickness, it is 99.6. I need help with parts A and B.
