  1. 0 of 250 30 Two pulses on a string approach each other at speeds of 1 m/s. What is the shape of the string at t = 6 s? C C A B

  2. 0 of 250 30 Fully destructive interference between two sinusoidal waves of the same frequency and amplitude occurs only if they: • Travel in opposite directions and are in phase • Travel in opposite directions and are 180o out of phase • Travel in same direction and are in phase • Travel in same direction and are 180o out of phase • Travel in same direction and are 90o out of phase • Set phaser to stun… who knows?!?

  3. 0 of 250 30 Which of the following represents a standing wave? • y(x,t) = 6 sin(3x+2t) – 6 cos(3x+2) • y(x,t) = 6 cos(3x-2t) + 6 cos(2t-3x) • y(x,t) = 6 cos(3x-2t) – 6 cos(2t-3) • y(x,t) = 6 sin(3x-2t) – 6 cos(2t+3x) • y(x,t) = 6 sin(3x) – 6 cos(2t)
