A student moves one end of a long rope up and down. A wave travels along the rope.
The Figure shows the shape of the rope at one instant.
Figure

Write down the amplitude of the wave.
Use the Figure to find the wavelength of the wave.
Define the term frequency.
The wave on the rope is a transverse wave.
Describe the direction in which the rope moves compared with the direction in which the wave travels.
