Question

identify the parts of the wave shown below.

Explanation:

1. The double-headed arrow between two corresponding points on adjacent wave cycles marks the wavelength (the distance of one full wave cycle).
2. The vertical double-headed arrow from the rest line to the peak of the wave marks the amplitude (the maximum displacement from the rest position).
3. The topmost dashed box encloses the highest point of the wave, which is a crest.
4. The bottom dashed box encloses the lowest point of the wave, which is a trough.

Answer:

• Left top dashed box: crest
• Right top dashed box: amplitude
• Bottom left dashed box: wavelength
• Bottom right dashed box: trough
