In the figure below (not to scale), let L = 1.20 m and d = 0.170 mm and assume the slit system is illuminated with monochromatic 560-nm light. Viewing screen (a) Calculate the phase difference between the two wave fronts arriving at P when 0 = 0.500°. rad (b) Calculate the phase difference between the two wave fronts arriving at P when y = 5.00 mm. rad (c) What is the value of 0 for which the phase difference is 0.333 rad? (d) What is the value of 0 for which the path difference is À / 4?
