Problem 4 In problem set 9, we briefly looked at how the intensity of light reaching the retina is strongly influenced by the pupil. In front of the pupil is the cornea and just behind is the lens, both of which work together to direct and focus light in the eye. Light first enters the eye through the cornea, is bent through the pupil, and then moves through the lens which is controlled by muscles...

Between this and the next assignment, we want to get a better under- standing of how light interacts with the eye. Here are two questions to get us started, focused on diffraction (i.e., the spreading of light when it passes through a narrow opening) A. To regulate the intensity of light reaching our retinas, our pupils1 change diameter anywhere from 2 mm in bright light to 8 mm in dim light. Find the angular resolution of the eye for 550...

The human ear canal has a typical length of about 2.2 cm and can be modeled as a tube open at one end and closed at the eardrum. a) Calculate the fundamental frequency that humans should be expected to hear best. Assume that the speed of sound is 345 m/s in air. Looking deeply down your friends throat, or perhaps looking at a photograph, you observe the vocal tract. At the bottom of the vocal tract, when you aren't swallowing,...
