Question

Highest point of wave is called

• A. Crest
• B. Trough
• C. Current
• D. Heave

Hint:

Think of a wave as a sine curve:
Maximum positive displacement = Crest.
Maximum negative displacement = Trough.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Ocean waves are oscillatory movements of the water surface, characterized by specific structural components like height, wavelength, frequency, and period.

Step 2: Detailed Explanation:
Let us define the anatomical parts of an ocean surface wave:
The Crest is the highest point or displacement of a wave above the undisturbed water level.
The Trough is the lowest point or maximum downward displacement of a wave below the undisturbed water level.
The Wave Height is the vertical distance between the crest and the trough.
The Wavelength is the horizontal distance between two consecutive crests or two consecutive troughs.
A Current refers to the continuous, directional flow of water, rather than the oscillation of a wave.
Heave refers to the vertical motion of a vessel or water body, rather than a point on a wave.
Therefore, the highest point of a wave is called the crest.

Step 3: Final Answer:
The highest point of a wave is called the Crest.
