See the image: The question is about a transverse wave traveling and reflecting off a fixed point.

Is it 2?

Answer 1

To determine the correct wave shape after 3 seconds, we need to consider the wave's movement and reflection:

1. The original wave is moving to the right at v=1v = 1v=1 m/s.
2. The fixed boundary at x=5x = 5x=5 causes the wave to reflect, inverting its shape.
3. After 3 seconds, the incident wave has traveled 3×1=33 \times 1 = 33×1=3 meters to the right.
4. The reflected wave moves to the left at v′=−1v' = -1v′=−1 m/s, so it has also traveled 3 meters to the left.

By analyzing the options, Option 2 appears to be correct because it correctly represents the reflected wave inverted and shifted appropriately.
