4- The illustration depicts a longitudinal wave. Longitudinal waves are waves in which the displacement through the medium is in the same direction of displacement of the wave, independent of the direction.

5- Energy transmitted in a definite direction and with a definite speed in traveling waves. This type of wave moves at constant speeds in the same direction.

6- A breaking wave is described as a wave that is not confined to the space along the medium.

7- Standing waves appear to vibrate in place. These are those waves in which certain points of the wave, called nodes, remain immobile.

8- If two waves with identical crests and troughs meet, a constructive interference is occurring.

It is referred as constructive interference to an overlap of two or more equal frequency waves, which when interfered create a new wave pattern of greater intensity (amplitude) whose peak is the antinode; after this point, they are again the same waves as before.
