Question 1) Two water waves of amplitudes 0.6 m and 0.8 m, respectively, arrive simultaneously at a buoy. What is the amplitude of the net wave if these two waves are completely in-phase (i.e., phase shift of zero)? If these two waves are completely out of phase (i.e., phase-shifted by 180 degrees)? O 0.2 m; 1.4 m O 0.2 m; 0.2 m O 1.0 m; 1.4 m O 1.4 m; 0.2 m O 1.4 m; 1.0 m Question 2 1 pts Can the midpoint of a guitar string be an antinode? Can it be a node? O yes; yes O yes; no O no; yes O no; no Question 3 1 pts Is the number of nodes for a normal mode of a string fixed at both ends always larger than the number of antinodes? If so, how much larger? yes; 1 more O yes; 2 more no
