Describe how diffraction of water takes place in narrow and wide gaps?

Diffraction of water occurs when water waves encounter an obstacle or a gap. In narrow gaps, such as a small opening in a dam or a narrow channel, the water waves are forced to bend and spread out as they pass through the gap. This bending of the waves is known as diffraction. The amount of diffraction that occurs in narrow gaps is dependent on the size of the gap and the wavelength of the water waves.

In wide gaps, such as a large opening in a dam or a wide river, the water waves are able to pass through without much bending or spreading out. This is because the gap is large enough to allow the waves to pass through without significant interference. As a result, there is minimal diffraction of the water waves in wide gaps.

Overall, diffraction of water waves is more pronounced in narrow gaps compared to wide gaps due to the constraints imposed by the size of the opening.
