Which of the following characteristics are correct about waves? 1. Wind causes waves to travel in the ocean. 2. The actual motion of water beneath the wave is not circular. 3. Steep waves are not fairly young ones and are probably formed by local winds. 4. The highest and lowest points of a wave are called the crest and trough respectively. Select the correct answer using the code below:

• The wind is the most frequent cause of waves. The friction between the wind and the surface of the water produces wind-driven waves, also known as surface waves. Hence statement 1 is correct.
• Below the waves, the water actually moves in a circular motion. That means that as the wave approaches, things are dragged up and forward and down and back as it passes. Hence statement 2 is incorrect.
• The crest and trough of a wave, respectively, are its highest and lowest surface portions. Hence statement 4 is correct.
• Young waves, such as steep waves, are most likely created by the nearby wind. Hence statement 3 is incorrect.

Waves

• The particles of the medium are not moved from one location to another as a wave travel across it. Only their equilibrium positions cause them to vibrate.
• Every particle in the medium moves similarly to the one before it.
• The only thing that moves during wave motion is energy.
• There are two types of waves: longitudinal and transverse.
• Without any actual material movement, a wave is a sort of disturbance that moves across a material medium as a result of the repeated motion of the medium's particle about its mean positions.
