Which of the following best shows the shape of the resultant pulse when the centers of the pulses, points P and Q, coincide? 009 10.0 points You are given f1(zr), a transverse wave that moves on a string that ends and is FIXED in place at a: = 5 m. As the problem begins, the wave is moving to the right at u = 1 m/s. Amplitude (centimeter) 012345678910 Distance (meter) Consider the image of the wave reected about the FIXED point a: = 5 m in the fol- lowing diagram. The image will be moving to the left at 12' = 1 m/s (in the opposite direction from the real wave). 0 'U r ( \"U; o Climb: | | M |' Amplitude (centimeter) | o: 012345678910 Distance (meter) What is the shape of the wave on the string after 3 s? qIIOIIII 012345678910 Distance (meter) poole (ep27476) - Homework 10, oscillations and waves 22-23 - tejeda - (MalikLPHY1_1) 3 2. 6. -2 -3 0 1 2 3 4 5 6 7 8 9 10 1 2 3 5 6 7 8 9 10 Distance (meter) Distance (meter) 3 7.
