What is the name given to the highest point of displacement in a transverse wave?

The highest point of displacement in a transverse wave is known as the crest. In a transverse wave, the wave motion is perpendicular to the direction of the energy transfer, causing the wave to have peaks and valleys. The peak, or crest, represents the maximum upward displacement from the rest position.

Understanding this concept is crucial when studying wave properties, as it distinguishes the crest from other features such as the trough, which is the lowest point of displacement, and the amplitude, which measures the height of the wave from the rest position to either the crest or trough. The node refers to points along the wave that remain stationary and do not experience displacement, typically found in standing waves. Each term describes different aspects of wave behavior, but the crest specifically indicates the highest point, making it essential for comprehending wave motion.
