TA: Tomoyuki Nakayama Monday, November 29, 2010 PHY 2048: Physics 1 with Calculus, Fall 2010 Review: Chapter 16.1-16.13 The purpose of this review is to refresh your memory. Physics is a cumulative subject, so make it sure you understand basic concepts and typical problem solving techniques in previous chapters before moving on to a new chapter! ________________________________________________________________________________ A. Traveling Waves A sinusoidal transverse wave of wavelength 20 cm travels along a string in + x direction. The displacement of the string element at x = 0 is given in the figure on the right, where y s = 5 cm. Assuming the wave function has a form of y (x,t) = y m sin( kx- ω t+ φ ), find y m , k, ω , φ and the speed of the wave. B. Interference & Standing Waves A nylon string with mass m = 15 g and length D = 60 cm is under a tension of 200 N. Calculate the speed, wavelength and frequency of traveling wave which produces the standing pattern shown in the figure.
