homework 14 – – Due: May 2 2007, 4:00 am 1 Question 1, chap 16, sect 3. part 1 of 1 8 points You are given two waves, a transverse wave that moves to the right f 1 ( x ) and a transverse wave that moves to the left f 2 ( x ), on a string. As the problem begins, the wave f 1 ( x ) is mov- ing to the right at v 1 = +1 m/s and the wave f 2 ( x ) is moving to the left at v 2 = 1 m/s. v 1 v 2 0 1 2 3 4 5 6 7 8 9 10 -3 -2 -1 0 1 2 3 Amplitude (centimeter) Distance (meter) What is the shape of the wave on the string after 2 s? 1. 0 1 2 3 4 5 6 7 8 9 10 -3 -2 -1 0 1 2 3 Distance (meter) 2. 0 1 2 3 4 5 6 7 8 9 10 -3 -2 -1 0 1 2 3 Distance (meter) correct 3. 0 1 2 3 4 5 6 7 8 9 10 -3 -2 -1 0 1 2 3 Distance (meter) 4. 0 1 2 3 4 5 6 7 8 9 10 -3 -2 -1 0 1 2 3 Distance (meter) 5. 0 1 2 3 4 5 6 7 8 9 10 -3 -2 -1 0 1 2 3 Distance (meter) 6. 0 1 2 3 4 5 6 7 8 9 10 -3 -2 -1 0 1 2 3 Distance (meter)
