Do NOT write on these sheets or take them with you! The next class needs them too! PHYS-1200 PHYSICS II SPRING 2005 Class 13 Activity: Mechanical Waves Before You Start 1. A general expression for a wave is y ( x , t ) = y m sin( kx ± ϖ t ). If a wave is moving to the right (toward positive x ), which sign should be used in the above expression? Explain your answer. 2. Which (if any) of the following parameters of the above wave will change as the wave moves: amplitude y m , shape (sinusoidal), wavelength λ , or speed v ? Taking Data Open and view movie Wave.mov in VideoPoint, as follows. Go to the course web page, then to “class activities”, scroll to the bottom and double click on the file. If the file opens in quicktime, rather than VideoPoint, save the file on your computer and reopen it VideoPoint.

### 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.
