⇨ Longitudinal Waves & Transverse Waves .
Longitudinal Waves .
Longitudinal waves are waves which travels in a direction parallel to the direction of vibrations. It is demonstrated by rapidly pushing and pulling the end of a slinky coil.Between successive compressions is a stretched region , known as rarefaction . The coils themselves do not travel , they just vibrate forward and back . One examples of longitudinal waves is sound waves.Mechanical longitudinal waves have been also referred to as compressional waves or compression waves.
Transverse Waves .
Transverse waves are waves which travels in a direction perpendicular to the direction of the vibrations. It is demonstrated by moving the end of a slinky coil up and down or from side to side . Light and other electromagnetic waves are also transverse waves . Waves ropes and rope waves are examples of transverse waves.
