VI. Test your understanding: The figure below shows a rope on a smooth floor with a knot at point A. Someone has shaken the end sideways to make a pulse. You are looking down and taking a movie of the motion. Below is one freeze frame of the movie. Underline your answer for each situation: 1. If you advance the movie one frame, the knot at point A would be a) in the same place b) higher c) lower d) to the right e) to the left 2. If the person generates a new pulse like the first but more quickly, the pulse would be a) same size b) wider c) narrower 3. If the person generates another pulse like the first but he moves his hand further, the pulse would be a) same size b) taller c) shorter 4. If the person generates another pulse like the first but the rope is tightened, the pulse will move a) at the same rate b) faster c) slower

Expert Solution
Step 1

1) The commotion is shifting to the right. As a result, point A will shift higher in the next frame.

So,

 Option B is correct 

 

2) The frequency of the pulse increases as it is generated swiftly. It has no effect on amplitude, though. As a result, the pulse would narrowed.

so, 

option C is correct.
