Draw neat, labelled diagrams of one complete transverse wave on a rope and one complete longitudinal wave in a spring placed side by side.
a. (a) On the transverse wave, label crest, trough, wavelength, and amplitude.
b. (b) On the longitudinal wave, label compression, rarefaction, and wavelength.
c. (c) Using your diagrams, describe how wavelength is measured in the two kinds of waves.
d. (d) Compare, with reference to your diagrams, how the amplitude of vibration is represented differently in transverse and longitudinal waves.
