A wave pulse travels along a horizontal string. As the pulse passes a pint on the string, the point moves 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.
