Compressional waves produce compression and rarefaction when traveling through a medium.Transverse wave displacements of the medium are at right angles to the direction of propagation.
Mechanical Waves are waves which propagate through a material medium (solid, liquid, or gas) at a wave speed which depends on the elastic and inertial properties of that medium. There are two basic types of wave motion for mechanical waves: longitudinal waves and transverse waves. The animations below demonstrate both types of wave and illustrate the difference between the motion of the wave and the motion of the particles in the medium through which the wave is travelling. The second animation at right shows the difference between the oscillatory motion of individual particles and the propagation of the wave through the medium. The animation also identifies the regions of compression and rarefaction. Mechanical longitudinal waves are also called compressional waves or compression waves, because they produce compression and rarefaction when traveling through a medium. The other main type of wave is the transverse wave, in which the displacements of the medium are at right angles to the direction of propagation. In longitudinal waves, the displacement of the medium is parallel to the propagation of the wave. A wave along the length of a stretched Slinky toy, where the distance between coils increases and decreases, is a good visualization. Sound waves in air are longitudinal, pressure waves. Longitudinal waves, also known as l-waves, are waves in which the displacement of the medium is in the same direction as, or the opposite direction to, the direction of travel of the wave. In longitudinal waves, the displacement of the medium is parallel to the propagation of the wave. A wave along the length of a stretched Slinky toy, where the distance between coils increases and decreases, is a good visualization. Sound waves in air are longitudinal, pressure waves. See information on P waves. Transverse Wave s. A transverse wave is a wave in which the motion of the medium is a right angles to the direction of the wave. A wave on a rope is a transverse wave. Light and other electromagnetic waves are also transverse waves. Longitudinal Waves. In a longitudinal wave, the motion of the medium is parallel to the direction of the wave. This means that the particles move left and right which in turn makes the other particles start to oscillate. Sound waves are longitudinal Transverse Waves. For transverse waves the displacement of the medium is perpendicular to the direction of propagation of the wave. A ripple on a pond and a wave on a string are easily visualized transverse waves.  They are both mechanical waves. In compressional waves the medium moves forward and backward along … the direction a wave travels. While, transverse waves the wave energy causes matter in the medium to move up and downor back and forth at right angles to the direction thw wave travels. Making the world better, one answer at a time. Transverse waves move at a right angle to the direction the wave travels, a compressional wave moves back and forth in the same direction the A transverse wave is a wave wherein the movement of the channel or medium is at a right angle to the wave’s direction. The particles move up and down as the wave moves horizontally. Electromagnetic waves and the secondary or S-wave in an earthquake are transverse waves. 1.A longitudinal wave is a wave wherein the movement of the medium is in the same direction as the wave while a transverse wave is a wave wherein the movement of the medium is at a right angle to the direction of the wave. Answered by The Community. Making the world better, one answer at a time. transverse waves-the medium vibrates up and down, example-visible light, gamma and xrays. compression/longitudinal-move back and forth and need a medium to travel in. example-slinky.
