The amplitude of a wave is measured as the distance from the equilibrium point (midpoint) of the wave to the crest (highest point) or trough (lowest point) of the wave. This can be measured using a ruler or measuring tape.
The unit of measurement for wavelength is meters (m). However, for smaller waves such as ripples on a pond, centimeters (cm) or millimeters (mm) may be used.
The frequency of a wave is measured in hertz (Hz), which represents the number of complete waves passing a fixed point in one second. This can be measured using a stopwatch and counting the number of waves passing a fixed point in one second.
In a transverse wave, the amplitude is measured as the distance from the equilibrium point to the crest or trough, while in a longitudinal wave, the amplitude is measured as the distance from the equilibrium point to the compression or rarefaction of the wave.
The speed of a wave can be calculated by dividing the wavelength by the period. The period is the time it takes for one complete wave to pass a fixed point. This can be measured using a stopwatch and counting the time it takes for a certain number of waves to pass a fixed point.
