WebJan 28, 2012 · Since 1 wave is 20m, the speed is v=d/t = 20m/4s = 5m/s. If one boat is on a trough while the other is on a peak with one peak between them, there must be 1.5 waves between the boats. Since the boats are 30m apart, 1 wave = 30m/1.5 = 20m (If you draw it, you can tell that a full wave occurs at 2/3 the distance between them. WebWhen this distance is an integral or half-integral multiple of the wavelength in the medium ( λ n = λ / n, where λ is the wavelength in vacuum and n is the index of refraction), … how to empty dyson cordless stick vacuum https://crofootgroup.com
