PHYSICS 309L, TEST 1, SPRING 2010 1) A person is creating a standing wave in a cylinder that is open at one end and closed at the other end. The height of the cylinder is 50 cm. What is the wavelength of the fundamental standing wave? Given the speed of sound, 340 m/s , what is the frequency of this wave? 2) A skipper on a boat notices wave crests passing his anchor chain every 4 s .He estimates the distance between the wave crests to be 16

### 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.
