When a standing wave is produced in a string fixed at both ends, the string oscillates so fast that it looks like a blur. You want to photograph the string when it is at positions A, B, and C shown in the figure. The tension in the string is 2.00 N and its mass per unit length is 0.200 g/m. The string's length is 0.720 m. Assume that you take your first picture when the string is in position A and let that be time t = 0. What are the first two times after t = 0 at which you can photograph the string in each of the positions A, B, and C?
