4. Two coherent point sources 7.5 cm apart create an interference pattern in a ripple tank. There are 8 nodal lines in the entire interference pattern. Determine the wavelength of the water waves.

+ Resolving Power of the Eye If you can read the bottom row of your doctor's eye chart, your eye has a resolving power of one arcminute, equal to 1.67x10² degrees. Part A fer Pain for PS do for Par 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 580 nm Express your answer in millimeters to three significant figures. ▸ View Available Hint(s) Submit Provide Feedback redo foart A reor Part A keyboard shortcuts for Part A help for Part A (<) mm.

Solve the problem applying Young's double split experiment.

(1) This ray diagram has a flaw. (True/False) (2) If the diagram has no flaw, determine in which medium the waves travel more quickly. OA. Top medium OB. Bottom medium C. Can not tell D. This diagram has a flaw.
