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.

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

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.
