  1. Chapter 13 - Waves

  2. The graph at the top is the history graph at x = 4 m of a wave traveling to the right at a speed of 2 m/s. Which is the history graph of this wave at x = 0 m?

  3. The graph at the top is the history graph at x = 4 m of a wave traveling to the right at a speed of 2 m/s. Which is the history graph of this wave at x = 0 m?

  4. Which of the following actions would make a pulse travel faster down a stretched string? • Move your hand up and down more quickly as you generate the pulse. • Move your hand up and down a larger distance as you generate the pulse. • Use a heavier string of the same length, under the same tension. • Use a lighter string of the same length, under the same tension. • Use a longer string of the same thickness, density and tension.

  8. What is the phase difference between the crest of a wave and the adjacent trough? • 0 • π/4 • π/2 • 3 π/2 • π

  10. A light wave travels through three transparent materials of equal thickness. Rank is order, from the largest to smallest, the indices of refraction n1, n2, and n3. • n2 > n1 > n3 • n3 > n1 > n2 • n1 > n2 > n3 • n3 > n2 > n1 • n1 = n2 = n3

  12. Amy and Zack are both listening to the source of sound waves that is moving to the right. Compare the frequencies each hears. • fAmy < fZack • fAmy = fZack • fAmy > fZack

  14. A graph showing wave displacement versus time at a specific point in space is called a • snapshot graph. • history graph. • bar graph. • line graph. • composite graph.

  16. A wave front diagram shows • the wavelengths of a wave. • the crests of a wave. • how the wave looks as it moves toward you. • the forces acting on a string that’s under tension. • Wave front diagrams were not discussed in this chapter.
