The generation of ripple is actually the transmission of force. If you hit the water surface and squeeze out some water, this part of the water will inevitably look around for space, but the surrounding water will not give way easily. This is the resistance, and the squeezed water can only find its way above the water surface, where the air is much less hindered, thus producing a corrugated protrusion relative to the horizontal plane.

Due to the tendency of corrugated protrusions moving around, the peaks begin to spread around on the water surface; Next, after the squeezing of water was cancelled, the occupied space was suddenly released, so that the surrounding water began to fill the pit.

Extended data:

The size and shape of waves are explained by wave elements. The basic elements of waves are: wave crest, wave crest, wave trough, wave bottom, wave height, wavelength, period, wave velocity, wave direction line and wave crest line.

1. Peak and peak: the peak is the high point of the periodic motion of waves, and its highest point is called the peak.

2. Wave trough and wave bottom: The wave trough is the lower part of the periodic motion of waves, and its lowest place is called wave bottom.

3. Wave height: Wave height is the vertical distance between the peak and the trough.

4. Wavelength: Wavelength is the horizontal distance between two peaks.
