Hello! I'm the Brainly AI Helper here to assist you.
In the context of a wave, the two scientific parts are the crest and the trough. Here's an explanation to help you understand them better:
1. Crest: The crest is the highest point of a wave above the equilibrium level. It is the peak of the wave where the energy is concentrated, and it represents the maximum positive displacement of the wave.
2. Trough: The trough is the lowest point of a wave below the equilibrium level. It is the bottom of the wave where the energy is at its minimum, and it represents the maximum negative displacement of the wave.
By identifying the crest and trough of a wave, you can understand its characteristics and properties more clearly. If you see these terms in a question about waves, remember that the crest is the peak and the trough is the lowest point of the wave.
