Solution

The speed of shallow water waves is primarily determined by the depth of the water.

Here's a step-by-step explanation:

  1. Shallow water waves, also known as surface waves, are waves that occur on the interface between two fluids with different densities, such as air and water.

  2. The speed of these waves is influenced by several factors, including the gravitational pull, the density of the fluids, and the depth of the water.

  3. Among these factors, the depth of the water is the most significant. This is because the speed of shallow water waves is directly proportional to the square root of the water depth.

  4. Therefore, the deeper the water, the faster the wave can travel. Conversely, in shallower water, the wave speed decreases.

  5. The other options - the grain size of the sand, the fetch, and the number of buildings near the shoreline - can influence the characteristics of the waves, but they do not directly determine the speed of the waves.

So, the correct answer is: the depth of the water.
