b) Wave properties

bi) displacement, amplitude, wavelength, period, phase difference, frequency and speed of a wave

amplitude = maximum displacement from the rest position

wavelength = distance between two adjacent points oscillating in phase on a wave

period = time taken for one wave cycle to pass a point

frequency = number of wave cycles that pass a point per unit time

wave speed = distance travelled by one wave cycle per unit time

phase difference = difference in displacement between

two waves

or

two particles on the same wave
