Unformatted text preview: Physics 2C, Waves ...Optics-- Winter 2007 Instructor: B. Grinstein Quiz # 2 INSTRUCTIONS: Fill, tear and return the bottom strip of the front page with your scantron. Keep the top portion of the front page and the rest of the quiz. Use a pencil #2 to ¡ll your scantron. Write your code number and bubble it in under "EXAM NUMBER". Bubble in the quiz form (see letter A-- D at bottom of page) in your scantron under "TEST FORM" Useful constants: c = 3.0 × 10 8 m/s, μ = 4 π × 10- 7 T · m 2 /A 1) A transverse wave is propagated in a string stretched along the x- axis. The equation of the wave, in SI units, is given by: y = 0.004 cos π (86t- 14x). The maximum velocity of a particle on the string, in SI units, is closest to: A) 2.5 B) 1.8 C) 1.4 D) 1.1 E) 2.1 2) A wave is traveling with a speed v along the x axis in the positive direction. The upper graph shows the displacement y versus the distance x for a given instant of time. The lower graph shows the displacement y versus the time t...
