Explanation:
Waves are the periodic disturbances in any medium. The common examples of waves are sound waves and water waves. In this figure, the several parts of waves have been described. Here, I will explain them one by one.
1. Consider a normal line, which we will take as a reference. We call it Equilibrium.
2. The vertical distance from Equilibrium to the highest or lowest point (also called peak points) of wave is called Amplitude.
3. The distance between two corresponding peak points is called Wavelength.
4. The lower part of the wave, which is below the equilibrium is called Trough.
5. The upper part of wave, which is above the equilibrium is called Crest.
6. Wavelength: As Explained in point 3
7. Trough: As Explained in point 4.
8. Crest: As Explained in point 5.
