Question:

In Figure 37.5 let L = 1.20 m and d = 0.120 mm and assume that the slit system is illuminated with monochromatic 500-nm light. Calculate the phase difference between the two wave fronts arriving at P when
(a) θ = 0.500° and
(b) y = 5.00 mm.
(c) What is the value of θ for which the phase difference is 0.333 rad?
(d) What is the value of θ for which the path difference is &/4?
