In physics, a transverse wave is a wave that oscillates perpendicularly to the direction of the wave's advance. In contrast, a longitudinal wave travels in the direction of its oscillations.
In a transverse wave, the atoms of the medium move perpendicular to the direction that the energy is moving through the medium. When the wave has passed, the atoms of the medium have returned to their equilibrium positions. All transverse waves share certain characteristics. Waves have an amplitude (A). The amplitude is how far from equilibrium ...
A simple transverse wave can be represented by a sine or cosine curve, so called because the amplitude of any point on the curve— i.e., its distance from the axis—is proportional to the sine (or cosine) of an angle. In the figure, sine curves of various amplitudes are shown.
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.
24 Απρ 2022 · The wave amplitude is large for a much broader range of \(x\) at \(y \) = 0 in this case, roughly -12 \(< x < \) 12. On the other hand, the subsequent spread of the wave is much smaller than in the case of figure 2.13.
This Lesson discusses details about the nature of a transverse and a longitudinal wave. Crests and troughs, compressions and rarefactions, and wavelength and amplitude are explained in great detail.
In the previous section, we described periodic waves by their characteristics of wavelength, period, amplitude, and wave speed of the wave. Waves can also be described by the motion of the particles of the medium through which the waves move.
