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 patterm. 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 m O 350 nm O 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).
