Ashley made the time measurements 3 diagram. The times show how long it takes for the troughs of these two identical waves to pass a certain point. What is the period of these waves?

• A-2 s

• B-4 s

• C 0.5 s

• D- 2 waves/s

The diagram below shows a wave pattern. What pa-4 of a wave is represented by B?

• A. crest

• B. trough

• C. amplitude

• D. wavelength

: The diagram below shows a wave pattern. Another 5 wave property that is shown is amplitude. Amplitude is to either the the vertical distance from the rest position crest or the trough of a wave. What is the rest position of a wave in the diagram?

• A. E

• B. F

• C. distance from G to H

• D . point that is halfway between G and H

Which property of a mechanical wave measures the amount of particle vibration?

• A. period
