Calm Waves on a Sand Beach

You are lying on the sundrenched beach facing the ocean. The gentle winds brush through your hair and also cause calm waves to appear on the surface of the water. You close your eyes and inhale the fresh salty air, and as you exhale all tension leaves your body. In fluid dynamics, wind waves or, more precisely, wind-generated waves are surface waves that occur on the free surface of oceans, seas, lakes, rivers, and canals or even on small puddles and ponds. They usually result from the wind blowing over a vast enough stretch of fluid surface. Waves in the oceans can travel thousands of miles before reaching land. Wind waves range in size from small ripples to huge waves over 30 m high.
