Question

Which of the following Period(s) correspond(s) to wind waves?

• A. 5 seconds
• B. 20 seconds
• C. 6 hours
• D. 12 hours

Hint:

Wind waves typically have short periods ranging from a few seconds to a maximum of 20 seconds. Tidal waves and other long-period ocean waves have much longer periods.

Answer 1

The Correct Option is A, B

Wind waves are typically characterized by short periods, usually ranging from a few seconds to about 20 seconds. This range corresponds to the time it takes for the wind to create the surface waves on the water. Therefore:
- 5 seconds and 20 seconds are typical periods for wind waves.
- 6 hours and 12 hours correspond to much longer periods, typically associated with tidal waves or other large-scale ocean waves, not wind-generated waves.
Thus, the correct answers are (A) 5 seconds and (B) 20 seconds.
