The drawings represent snapshots taken of waves traveling to the right along strings. The grids shown in the background are identical. The waves all have the same speed, but their amplitudes vary.

Which image(s) has the biggest wavelength?

If a tie, pick all that apply.

• A

• B

• C

• D

The drawings represent snapshots taken of waves traveling along a rope. The grids shown in the background are identical.

These pulses, which vary in amplitude, are all sent down identical ropes under equal tension. The ropes are all the same length, and there is no distortion of the pulses as they travel down the ropes.

Which wave gets to the end of the 3m rope first?

If a tie, pick all that apply.

• A

• B

• C

• D
