The lowest point is called the trough. The distance from one crest to the next is the wave length. The number of waves that pass a given point in one second is the wave's frequency. When wind blows over the ocean's surface, it creates waves. Their size depends on how far, how fast and how long the wind blows.
When you are standing against the wind, no matter how loud you shout, your distant friend cannot hear you at all, but you can hear him very well. Does wind scatter sound wave? Surprisingly, this phenomenon is related to refraction! Sound wave travels faster in the air when it is with the wind. Generally speaking, wind speed is lower near the ground because of the presence of blockages, and so it increases with height (Fig. 1). Therefore, when traveling with the wind, sound wave farther from the ground travels faster.
