You will have learned how to analyse the properties of a wave, such as amplitude and wavelength, in “General Wave Properties”. The diagram below shows the equivalent of a wavelength on a longitudinal wave. Wavelength shown on a longitudinal wave.
The wave can be described as having a vertical distance of 32 cm from a trough to a crest, a frequency of 2.4 Hz, and a horizontal distance of 48 cm from a crest to the nearest trough. Determine the amplitude, period, and wavelength of such a wave. See Answer. Amplitude = 16 cm.
The longitudinal waves in an earthquake are called pressure waves (P-waves) and the transverse waves are called shear waves (S-waves). These two types of waves propagate at different speeds, and the speed at which they travel depends on the rigidity of the medium through which they are traveling.
In a longitudinal wave, the distance from the equilibrium position in the medium to compression or rarefaction is the amplitude. Period and Frequency. The time taken by the wave to move one wavelength is known as the period. The frequency of the longitudinal wave is the number of wavelengths per second.
Physics. Graphical Representations of Transverse & Longitudinal Waves. Transverse and longitudinal waves can be represented graphically. Transverse Waves. Transverse waves show areas of crests (peaks) and troughs. Diagram of a transverse wave. The peaks are the maximum positive displacements. The troughs are the maximum negative displacements.
Learning Objectives. Explain how energy travels with a pulse or wave. Describe, using a mathematical expression, how the energy in a wave depends on the amplitude of the wave. All waves carry energy, and sometimes this can be directly observed.
