Displacement-distance A displacement-distance graph is a snapshot of the wave at any given time. You should be able to work out the wavelength of a wave from a displacement-time graph.

Revise waves, which are oscillations or vibrations about a rest position. Waves can be longitudinal or transverse. Draw a displacement-distance graph.

Kinematical Graphs The ‘displacement-time’ and the ‘velocity-time’ graphs of a particle are often used to provide us with avisual representation of the motion of a particle.
