According to the rules of wave magnitude speed and motion, the magnitude of the orbit of the water molecules is proportional to depth and orbital motion a depth equal to 1/2 of the wavelength. Hence in order to feel bottom, the wavelength necessary should be less than or equal to the 1/2 of the wavelength.

When the water depth affects the properties of waves, we call it as feels bottom. Given the wavelength, we can have an approximation that the ocean floor must be as shallow as the half of the wavelength in order to consider it as feels bottom. Therefore, getting the half of the given wavelength, ocean floor must have an ideal depth of 10 feet.
