Physics 315: Oscillations and Waves Homework 9: Due in class on Wednesday, Nov. 25th 1. An interference experiment employs two narrow parallel slits of separation 0 . 25 mm, and monochromatic light of wavelength λ = 500 nm. Estimate the minimum distance that the projection screen must be placed behind the slits in order to obtain a far-field interference pattern. 2. A double-slit of slit separation 0 . 5 mm is illuminated at normal incidence by a parallel beam from a helium-neon laser that emits monochromatic light of wavelength 632 . 8 nm. A projection screen is located 5 m behind the slit. What is the separation of the central interference fringes on the screen? 3. Consider a double-slit interference experiment in which the slit spacing is 0 . 1 mm, and the projection screen is located 50 cm behind the slits. As- suming monochromatic illumination at normal incidence, if the observed separation between neighboring interference maxima at the center of the projection screen is 2 .

### What students are saying

• 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.
