Sound waves are longitudinal waves, and it's easy to imagine alternating layers of compression zones. We deal with this all the time with freeway traffic jams. Electromagnetic waves, however, are examples of traversal waves, and it helps to first understand that nothing is being compressed. Now, early hard drive media involved shifting the direction of magnetic lines on the surface and parallel to it, which we can schematically represent with arrows showing the magnetic vector field. An electric field has the power to shift the magnetic field. Now, imagine stacking a long bundle of such hard drive discs, each one having a magnetic vector field direction. A CHANGE in any one of the magnetic vector field actually creates or changes an electric field, which in turn can induce a change in the magnetic field in the NEXT disc. Do you get the idea now? A ripple effect through the discs can be created, creating an moving interplay of magnetic and electric fields. Since all the changes in vector direction of both magnetic and electric fields are perpendicular to the stack axis of discs, or direction of the wave, this electromagnetic wave is called a traverse wave.

Its stressful to describe this with out occasion... yet 1st theoretically ... i) Sound waves circulate in longitudinal waves and in basic terms sound do this different(mild or water) circulate in transverse waves. ii) Longitudinal waves circulate parallel from the source of propagation whilst traverse wave circulate perpendicular from the source of propagation. occasion you recognize what's slinky? think of u are protecting one end of the slinky and the different hand is carry by potential of something Longitudinal waves are like u push the slinky front and backward forming the wave. Traverse waves are like u shake the slinky up and right down to type a waves...

Transverse wave is the wave which propagated forwards by wave particles vibrate in up and down manner. For longitudinal wave, wave particles vibrate in direction forward and backward.

If a sideways movement of a molecule causes a sideways movement of a neighboring molecule, then transverse waves are possible. It happens for sound waves in solids (where molecules are rigidly connected to each other) but not in liquids or gases (where only longitudinal sound waves are possible).

The best way to visualize this is to imagine yourself holding one end of a rope, the other end of which is fixed to a wall. Move your end of the rope up and down. You will see waves moving down the rope, travelling toward the wall. However, the rope is only moving up and down, perpendicular to the motion of the waves. The wave "motion" is only the peak amplitude of lateral rope displacement appearing at different locations in time.
