Consider the following statements with reference to sea waves: 1. The height of waves is determined by wind speed, wind duration, and fetch 2. The energy of a wave is proportional to the square of its height 3. Waves retain most of their energy as they travel across the deep ocean Which of the statements given above is/are correct?

Options

  1. A1 only
  2. B1 and 2 only
  3. C2 and 3 only
  4. D1, 2 and 3

Correct answer

D. 1, 2 and 3

Step-by-step solution

The height of sea waves is primarily determined by three factors: wind speed, the duration for which the wind blows, and the fetch (the distance of open water over which the wind blows). Thus, statement 1 is correct. The energy of a wave is directly proportional to the square of its height ( E H^2 ). Thus, statement 2 is correct. As waves travel across the deep ocean, they experience very little friction because the water depth is much greater than the wave base. Consequently, they retain most of their energy and c
