Vertically up and then back down again. how does the vertical speed of the point compare to the speed of the wave? • the speed of the point equals the speed multiplied by the wavelength and divided by the string's length.• the wave speed equals the point speed multiplies by the wavelength and divided by the string's length.• the speed of the point is 2 times greater than the wave speed.• the speed of the point could be neglected compared to the wave speed.• the wave speed could be neglected compared to the speed of the point.• the speeds could not be uniquely compared, because there is no fixed relationship between them.
