The diagram shows one frame of a movie of a wave travelling along a string. If you advance the movie one frame, the knot at point A would be:
A. in the same place
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
If the person generates another pulse like the first but he moves his hand further, the pulse would be:
If the person generates another pulse like the first
but the rope is tightened, the pulse will move
A. at the same rate
If you advance the movie one frame, the knot at point A would be:
If you advance the movie one frame, the pattern of the waves will be _________relative to the hand.
B. shifted right
C. shifted left
D. shifted up
E. shifted down
If the person starts over and moves his hand more quickly, the peaks of the waves will be:
A. the same distance apart
B. further apart
C. closer together
8.If you lower the frequency of a wave on a string you will:
A. lower its speed.
B. increase its wavelength.
C. lower its amplitude.
D. shorten its period.
