A wave is established in a rope. The diagram below represents a 'snapshot' of the pattern in the rope at a given instant in time. Several points on the rope are labeled with a letter. Identify the letters of any wave troughs. List all that apply ... .

A wave trough of a wave is a location along the medium that is displaced a maximum negativedistance belowits original resting position.

A wave involves the repeating and periodic vibration of a medium. As each particle of the medium undergoes its up and down (or back and forth) vibration, the familiar wavelike pattern is established in the medium. At any given instant in time, there are positions along the medium that are displaced upward and positions along the medium that are displaced downward. A position of maximum upward displacement on the pattern is referred to as a crest. A position of maximum downward displacement on the pattern is referred to as a trough.
