1 . [1 point, 10 tries] In a location where the speed of sound is 329 m/s, a 1955 Hz sound wave impinges on two slits 33.9 cm apart. At what angle is the first-order maximum located? Answer: 2.98e+01 deg 2 2 . [1 point, 10 tries] If the sound wave is replaced by 3.46 cm microwaves, what slit separation gives the same angle for the first-order maximum? Answer: 6.97e-02 m 2 3 . [1 point, 10 tries] If the slit separation is 1.38 µm, what frequency of light gives the same first maximum angle? Answer: 4.38e+14 Hz 2 4 . [1 point, 10 tries] The intensity on the screen at a certain point in a double-slit interference pattern is 64.9% of the maximum value. What minimum phase difference (in radians) between sources produces this result? Answer: 1.27e+00 rad 2 5 . [1 point, 10 tries] Express the phase difference as a path difference for 489 nm light. Answer: 9.87e-08 m 2 6 . [1 point, 10 tries] A beam of 578 nm light passes through two closely spaced glass plates, as shown in the figure below.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
