What is the crest of a wave?

The lowest point of a wave
The highest point of a wave
The midpoint of a wave
The amplitude of a wave

The correct answer is: The highest point of a wave

The crest of a wave refers to the highest point in the wave cycle. In the context of waves, it is a crucial concept because it indicates the maximum displacement from the rest position when the wave travels through its medium, whether it's water, sound, or electromagnetic waves. Understanding the crest is essential in various applications, such as predicting how waves interact with each other or with their environment, which is fundamental in fields like oceanography, acoustics, and engineering. The crest is contrasted with the trough, which represents the lowest point of the wave, highlighting the wave's full oscillatory nature.
