We can distinguish between two classes of waves, based on the motion of the medium through which it propagates. With transverse waves, the elements of the medium oscillate back and forth in a direction perpendicular to the motion of the wave.
14 Μαΐ 2023 · No matter whether you are talking about vibrations or waves, all of them can be characterized by the following four characteristics: amplitude, wavelength, frequency, and speed. The amplitude of a wave can be described as the maximum distance the molecules are displaced from their starting place .
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.
Below is a model of a wave. A wave’s crest is its highest point, and its trough is its lowest point. A wave’s amplitude is the maximum distance (positive or negative) a wave reaches from its rest position. Wavelength is the distance between the same spot on two sections of a wave.
Characteristics of Waves. Waves have certain characteristic properties which are observable at first notice. The first property to note is the amplitude. The amplitude is half of the distance measured from crest to trough. We also observe the wavelength, which is the spatial period of the wave (e.g. from crest to crest or trough to trough).
Define mechanical waves and medium, and relate the two; Distinguish a pulse wave from a periodic wave; Distinguish a longitudinal wave from a transverse wave and give examples of such waves
The most common type of waves we encounter in our daily lives are mechanical waves. These include sound waves and wave motion in a string. Sound waves are an example of a travelling wave whereas a wave propagating in a string is an example of a standing wave.
