Physics 112: Wave Interference

http://kingfish.coastal.edu/physics/physlets/Waves/superposition.html

Play with the values to see the different wave forms (speed, wavelength, frequency, etc). The interference examples shown in class are below: Standing Wave f(x,t) = 2.5*sin(2.0*x + 8.0*t) g(x,t) = 2.5*sin(2.0*x - 8.0*t) Beat f(x,t) = 3.5*sin(8.5*x - 25.0*t) g(x,t) = 2.5*sin(9.5*x - 5.0*t) Walking Waves f(x,t) = 4.0*sin(8.0*x - 10.0*t) g(x,t) = 2.0*sin(10.5*x + 10.0*t)

Thursday, Sept. 23/2010: School Dance Tonight!

Physics 112 Discussed standing waves in 1, 2, and 3D. Our main focus will be standing waves in 1D (along a string). Check out the links (see Web Links) for wave interference and standing waves simulations and videos. Test moved to Wednesday, Sept. 29 Physics 122 Newton's second law. Read Pg 154 - 167. Questions Pg 163 #1 - 3 and Pg 168 #4 - 8. Handout Problems (not downloadable) Monday will be review. All questions should be completed so that you know what you need help with. Test Tuesday, Sept 28. Comp Sci 110 Review notes for chapter 1 and 2. Chapter 2 quiz is Friday. Ensure first three assignments are completed and submitted.
